Question

225. There are two solutions A and B. The pH of solution A is 5.5 and that of solution B is 10.

(a) Which one has more H⁺ concentration?

Answer 1

• pH determines the concentration of hydrogen ions (H⁺) in a solution.
• The strength of acids and bases depends on their pH values.
• The more acidic solution consists of low pH values and the more basic solutions consist of higher pH values.
• The solutions having pH values ranging from 0 to 7 are termed acids.
• The solutions having pH values ranging from 7 to 14 are termed bases.
• The solutions having pH values of exactly 7 are termed neutral.
• Acids will have a higher concentration of H⁺ ions.
• Solution A has a low value of pH which means it is more acidic and has more concentration of H⁺ ions.
• Hence, solution A has more H⁺ concentration.
