Question

Compared to a solution with a ph of 6, the hydronium ion concentration of a solution with a Ph of 4 has how many more times the concentration of hydronium ions ?

Answer 1

Answer: The hydronium ion concentration of a solution with a pH of 4 is 100 times more than the the hydronium ion concentration of a solution with a pH of 6

Explanation:

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

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

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

1. Solution with pH of 6

$6=-\log [H^+]$

$[H^+]=10^{-6}$

2. Solution with pH of 4

$4=-\log [H^+]$

$[H^+]=10^{-4}$

$\frac{H^+_4}{H^+_6}=\frac{10^{-4}}{10^{-6}}=10^{2}={100}$

${H^+_4}=100\times {H^+_6}$

Thus the hydronium ion concentration of a solution with a pH of 4 is 100 times more than the the hydronium ion concentration of a solution with a pH of 6
