Calculate the pHpH of a 0.10 MM solution of HClHCl . Express your answer numerically using two decimal places.
alisha [4.7K]

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

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 =\frac{1}{1}\times 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
