Stoichiometry - Engineering

Q1:

Two solutions A1 and A2 have pH value of 2 and 6 respectively. It implies that the solution

A A2 is more alkaline than solution A2

B A1 is highly acidic.

C A1 is very slightly acidic.

D both (a) &(c).

ANS:D - both (a) &(c).

The pH scale is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. A lower pH value indicates a more acidic solution, while a higher pH value indicates a more basic (alkaline) solution. In this case:

  • Solution A1 with a pH of 2 is more acidic than solution A2 with a pH of 6.
  • Solution A2 with a pH of 6 is more basic (alkaline) than solution A1 with a pH of 2.
So, the correct interpretation is: "Solution A2 is more alkaline than solution A1."
