Question

Calculate the pHpH of a 0.10 MM solution of HClHCl . Express your answer numerically using two decimal places.

Answer 1

Answer: The pH 0f 0.10 solution of HCl is 1.00

Step-by-step 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^+]`

`HCl\rightarrow H^++Cl^(-)`

According to stoichiometry,

1 mole of
`HCl` gives 1 mole of
`H^+`

Thus
`0.10` moles of
`HCl` gives =
`(1)/(1)* 0.10=0.10` moles of
`H^+`

Putting in the values:

`pH=-\log[0.10]`

`pH=1.00`

Thus pH 0f 0.10 solution of HCl is 1.00
