Question

You have two solutions A and B. The pH of solution A is 6 and pH of solution B is 8. Which solution has more hydrogen ion concentration? Give reason

Answer 1

As the meaning of pH is potense hydrogen means potential of hudrogen which means concentration of hydrogen in given compound. So as the pH level insreases concentration of hydrogen also increases. So solution B has more hydrogen concentration.

Answer 2

Answer: Solution A

Explanation:

pH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

$pH=-\log [H^+]$

$pH=log\frac {1}{H^+}$

A. pH = 6, $[H^+]=10^{-6}M$

B. pH = 8, $[H^+]=10^{-8}M$

Thus as pH and $H^+$ are inversely related, a solution having lower pH will have more amount of $H^+$ concentration. And a solution having more pH will have less amount of $H^+$ concentration.

Thus solution A with pH of 6 will have more amount of $H^+$ concentration than solution B with pH of 8.
