Can You Crack the Code to Escape the Lab?

To escape, you must complete five chemistry challenges covering pH, neutralisation, and household substances. Every correct answer reveals a hidden digit. Note these down carefully; you’ll need the full code to unlock the final door and win!

Acids and Alkalis

Acids range from pH 0 to 6, with lower numbers indicating stronger acidity. Alkalis range from pH 8 to 14, where higher numbers represent stronger alkalinity. Neutral substances, like pure water, sit perfectly at pH 7. Understanding this balance is your first step in navigating the lab safely.

Indicators are chemical tools that change color depending on the pH of a substance. Universal Indicator provides a spectrum of results: deep reds for strong acids, green for neutral solutions, and dark purples for strong alkalis. Use these color cues to identify the mystery samples in your path.

pH Guide

Lab Escaped!

You have mastered pH, neutralisation, and salt formation! Enter your 5-digit code to unlock the final doors. Keep exploring the fascinating world of chemical reactions as a true Chemistry Master.

Universal Indicator shows the pH value through specific color changes:

  • Acids: Strong acids appear red (pH 0-3), while weaker ones turn orange or yellow.
  • Neutral: A distinct green color indicates a pH of exactly 7.
  • Alkalis: These range from blue for weak alkalis to deep purple for the strongest bases.
Memorize these colors; they are the secret to finding the hidden escape room codes.
