##Chapter 05: First Day, First Impression (part-02)##
The double period after lunch was in the Pharmaceutical Analysis lab. As Arjun and Kavya joined the throng of students putting on their new, stiff white lab coats for the first time, the atmosphere shifted. The air smelled sharp and clean, a mix of ethanol and something metallic. This room was less about woodworking benches and more about gleaming countertops, faucets at every station, and glass cabinets filled with intimidatingly complex glassware.
Arjun's hands felt clumsy as he buttoned his coat. He was an imposter. A fraud who could talk the talk but had no idea if he could walk the walk. The System could tell him what to do, but it couldn't steady his hands.
Their instructor, Dr. Balwant Singh, was a tall, imposing man with a formidable turban and a gaze that seemed to miss nothing. He stood with his arms crossed, watching the students settle in.
"Welcome to Pharmaceutical Analysis," he began, his voice a low baritone that cut through the nervous chatter. "In this lab, sloppiness can have consequences. Not for you, not today. But for a patient, years from now, who takes a drug you failed to properly analyze. Precision is not a goal here. It is the only standard. Understood?"
A chorus of "Yes, sir" mumbled through the lab.
"Today, we perform your first official test from the Indian Pharmacopoeia. A simple, fundamental quality control procedure: the Limit Test for Chlorides."
He gestured to the reagent shelf. "The principle is simple. We add silver nitrate to a solution of the substance being tested. If chloride impurities are present, they will react to form insoluble silver chloride, which produces a cloudiness, or 'opalescence'. We compare this opalescence to a standard solution containing a known, permissible amount of chloride. If your test solution is less opalescent than the standard, the sample passes. If it is more opalescent, it fails. It is a visual, qualitative test of purity."
Dr. Singh pointed to the procedure written on the whiteboard. "You will work in pairs. One of you will prepare the 'Test Solution' with the provided sodium chloride sample. The other will prepare the 'Standard Solution'. Follow the procedure exactly. You have 45 minutes. Begin."
"I'll take the Standard," Kavya said to Arjun, already moving confidently toward the glassware cabinet. "You take the Test? It's the same procedure, just a different sample."
"Sure," Arjun croaked, his mouth suddenly dry.
*Task Requirement #3: Successfully perform the preliminary 'Limit Test for Chlorides' with less than 5% procedural error.*
He walked to his station, his movements stiff. He needed two 50mL Nessler cylinders—tall, perfectly matched glass cylinders used for color and turbidity comparison. He placed them in their stand.
The System flared to life, overlaying a checklist in his vision.
**[Procedure: Limit Test for Chlorides (IP)]**
**1. Pipette 1.0 mL of the provided sample solution into Nessler Cylinder labeled 'Test'.**
**2. Add 10 mL of distilled water.**
**3. Add 1 mL of dilute Nitric Acid.**
**4. Dilute to 50 mL with distilled water.**
**5. Add 1 mL of Silver Nitrate solution.**
**6. Stir immediately with a glass rod. Allow to stand for 5 minutes, protected from light.**
**7. Observe opalescence against a black background.**
It seemed simple enough on screen. But then he picked up the pipette. His hand trembled.
He tried to draw 1.0 mL of the sample solution. The liquid line wobbled in the glass tube.
**[WARNING: PARALLAX ERROR IMMINENT. VIEW MENISCUS AT EYE LEVEL. CURRENT ANGLE WILL RESULT IN 8% VOLUME ERROR.]**
Arjun froze. He adjusted his stance, crouching slightly to bring his eyes level with the pipette markings, just as the System suggested. He carefully released the pressure, letting the bottom of the curved liquid surface rest perfectly on the 1mL line. He transferred it to the Nessler cylinder. A tiny bead of sweat rolled down his temple.
He moved to the next step: adding 10 mL of distilled water with a measuring cylinder. Again, his hands felt clumsy. He started to pour too fast.
**[WARNING: EXCESSIVE FLOW RATE. RISK OF SPLASHING AND SAMPLE LOSS.]**
He slowed down, his movements becoming more deliberate, guided by the invisible tutor in his mind. He added the nitric acid, then diluted the solution to the 50mL mark on the cylinder. A faint blue line shimmered in his vision, showing him the exact target. Perfect.
Across the bench, Kavya was already a step ahead, adding her silver nitrate. She was a natural, quick and efficient.
Arjun took a breath and reached for the silver nitrate bottle.
**[CRITICAL STEP: ADD REAGENT AND STIR IMMEDIATELY TO ENSURE UNIFORM PARTICLE FORMATION OF SILVER CHLORIDE.]**
He added the 1mL of silver nitrate. As soon as the last drop fell, he picked up the glass rod and stirred, his motion smooth and even. He placed the cylinder back in its stand next to Kavya's. Now, they had to wait five minutes.
"Nervous?" Kavya asked quietly, cleaning her workstation.
"A bit," Arjun admitted, which was the understatement of the century.
"You were amazing in the lectures today, you know," she said. "Like, seriously amazing. I was struggling to just understand Dr. Mehra's question, and you were talking about drug side effects."
"Just... got lucky, I guess."
"I don't think that was luck." She gave him a curious, appraising look. "There's more to you than that 'medical store' story, isn't there?"
Before he could answer, Dr. Singh's voice boomed. "Five minutes are up. Bring your cylinders and observe them against the black background."
This was it. The moment of truth.
Arjun and Kavya carried their paired cylinders to the viewing station. It was simply a black-painted board at the back of the lab.
Arjun held the two Nessler cylinders side-by-side. Kavya's, labeled 'Standard', was distinctly cloudy, a milky opalescence suspended in the water. That was the acceptable limit.
He looked at his own cylinder, labeled 'Test'.
It was almost perfectly clear.
There was the faintest wisp of haziness, visible only because he was looking for it, but compared to the standard, it was like looking at spring water next to milk. The sample passed. Easily.
**[Procedural Error Calculated: 1.2%. Task Requirement 3/3 Met.]**
A wave of relief so powerful it made him dizzy washed over Arjun.
Dr. Singh was making his rounds, his sharp eyes inspecting each pair of cylinders. He stopped at their station. He picked up Arjun's and Kavya's cylinders, holding them to the light, then against the black board. He looked at Arjun.
"Explain your observation, Mr. Mehta."
"Sir," Arjun said, his voice steady now. "The opalescence produced in the test solution is significantly less than that of the standard solution."
"And your conclusion?"
"The sample passes the limit test for chlorides as per the Indian Pharmacopoeia."
Dr. Singh gave a single, curt nod. "Correct. Good technique. Clean your glassware and workstations." He moved on.
From Dr. Singh, that was the highest praise imaginable. Kavya beamed at him. "We did it! See? I told you it would be fine."
But for Arjun, it was more than fine. It was transformative. As he rinsed his glassware, a final, beautiful notification blossomed in his vision.

He had done it. He had survived his first day. More than survived, he had excelled. He felt the fear recede, replaced by a thrilling sense of power. He focused his thoughts on the newly unlocked function.
*Knowledge Database,* he thought. *Search: "Ranitidine".*
Instantly, the information that had flashed before him in the medical room yesterday appeared again, but this time it was on his command. He could scroll, expand sections, look at its chemical structure, mechanism of action, everything.
The lab, the students, the world around him seemed to fade for a second. He was no longer just a reluctant student. He was a boy with a library of Alexandria for pharmaceutical science hidden behind his eyes. And he had just learned how to turn the first page.
To be continue.
