Rearrange the following equation and solve for x when the hydrogen ion concentration is 0.001 m.

ph= 2 + log x

(recall that ph=−log[h+].)

answer choices: x= 10, x= 0.20, x= 3

Answer : The correct option is, x = 10

Explanation : Given,

Concentration of ion = 0.001 M

pH : It is defined as the negative logarithm of hydrogen ion or hydronium ion concentration.

First we have to calculate the pH.

Now we have to calculate we the value of 'x'.

The given expression is:

Now put the value of pH in this expression, we get:

Therefore, the value of 'x' is 10.
