easy Q2 of 15
General Science - Physics (Basics)
What is the pH of a strong acid solution?
AGreater than 7
BEqual to 7
CExactly 7.5
DLess than 7
Step-by-Step Solution
  1. Step 1: Recall pH scale basics

    The pH scale ranges from 0 to 14, where values less than 7 indicate acidic solutions.
  2. Step 2: Apply to strong acids

    Strong acids have high concentration of H+ ions, resulting in pH less than 7, often close to 0.
  3. Final Answer:

    Less than 7 → Option D
  4. Quick Check:

    Strong acid pH = Less than 7 ✅
Quick Trick: Acidic solutions have pH below 7.
Common Mistakes:
  • Mistaking acidic pH for neutral or basic values.
