A solution of ph6 contains __________ h+ than the same amount of a solution of ph8
Sholpan [36]

Answer:

A solution at pH 6 contains<u><em> 100 times more H+</em></u> than the same amount of solution at pH 8.

Explanation:

pH of a substance determines the hydrogen ion concentration of a solution. Acidic solution tend to have a higher concentration of H+ ions as compared to that of water. They have a concentration greater than 1 × 10^{-7}  M. Basic solutions have lesser concentration of H+ ions as compared to that of water. They have a concentration lesser than 1 × 10^{-7} M. A solution from pH range 1 to 6 will be acidic. A solution from pH rage 8-10 will be basic.
