Question

A solution of pH = 2 is more acidic than that of pH = 6 by a factor of

1)4 2) 12

3)400 4)10000



**plzzz give me the full explaintion for the correct answer.:) !

Answer 1

Answer: 4) 10000

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

It is defined as the negative logarithm of hydrogen ion concentration. Thus higher is the $H^+$ concentration higher is the acidity.

$pH=-log[H^+]$

1.  Thus for pH= 2, $2=-log[H^+]$

$[H^+]=10^{-2}M$

2.  Thus for pH= 6, $6=-log[H^+]$

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

$\frac{10^{-2}}{10^{-6}}=10^4$

Thus A solution of pH = 2 is more acidic than that of pH = 6 by a factor of 10000.

Answer 2

Answer:

${10}^{4} = 10000$
