Question description

If I have 1000 ml of an aqueous HCL solution of pH 3.5, how many grams of NaHCO3 are necessary to raise the pH to 7.2? About how long for this to occur with powdered bicarb at 20 degrees Centigrade? What is the reaction formula? If the density of the powdered bicarb is 1.1, what volume of bicarb is necessary? Thanks.

Hello! I wrote the solution on a PDF format instead for readability. Please check the file for your review :)

The chemical reaction for this is the following:
HCl + NaHCO3 → NaCl (aq) + CO2(g) + H20(l)
The initial hydrogen ion concentration is: (pH = 3.5)
[H+]i = 10-3.5 = 3.16228 x 10-4 M
The required final hydrogen ion concentration is: (pH = 7.2)
