Chapter 16, Problem 82IAE

Interpretation Introduction

Interpretation:

The molarity of the HCl solution needs to be calculated if the pH of saturated $\text{Sr}{\left(\text{OH}\right)}_{\text{2}}$ solution is 13.12. The volume of sample solution is 10.0 mL which is diluted to 250.0 mL. Again, to 10.0 mL of the diluted $\text{Sr}{\left(\text{OH}\right)}_{\text{2}}$ solution more water is added and the solution so formed needs 25.1 mL of HCl in titration.

Concept introduction:

As per the Bronsted-Lowry theory of bases and acids, proton acceptors are bases and proton donors are acids. Molecule which can either accept or donate the proton are known as amphiprotic. So, an amphiprotic act as either base or acid. Hydrogen sulfate ion, hydrogen carbonate ion, amino acids and water are common illustrations of amphiprotic molecules. Because they might donate the proton, all the amphiprotic species have hydrogen atom.

Molarity of any solution is defined as number of moles of solute in 1 L of the solution.
