Answer:
There will 3.95 grams of Na2 and H2O that should be added to form a concentric required solution.
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.
According to stoichiometry,
1 mole of
gives 1 mole of
Thus
moles of
gives =
moles of
Putting in the values:
Thus pH 0f 0.10 solution of HCl is 1.00
