Question

. Вычислите концентрацию ионов водорода в растворе, рН которого равен 10,25.

Answer 1

PH = -lg[H+], отсюда находим концентрацию ионов водорода:
[H+] = $10^{-pH}$ = $10^{-10,25}$ = 5,62*$10^{-11}$ моль/л

Answer 2

Calculating the Hydrogen Ion Concentration (pH) of a Solution

To calculate the concentration of hydrogen ions (H+) in a solution, we can use the pH value. The pH is a measure of the acidity or alkalinity of a solution and is defined as the negative logarithm (base 10) of the hydrogen ion concentration.

In this case, we are given a pH value of 10.25 and we need to calculate the hydrogen ion concentration.

To calculate the hydrogen ion concentration (C), we can use the formula:

C = 10^(-pH)

Let's substitute the given pH value into the formula:

C = 10^(-10.25)

Calculating this value, we find that the hydrogen ion concentration in the solution is approximately 5.62 x 10^(-11) M.

Please note that the concentration is given in molarity (M), which represents the number of moles of solute per liter of solution.
