Concept explainers

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

What is the concentration of Zn²⁺ in parts per million when 0.076 g of the chloride salt is dissolved in 899.76 mL of water? The density of water is 1.0 g/mL.

Expert Solution

Step 1

Well, since it is given chloride salt, and it contains zink so the salt must be ZnCl₂.

We know

Mass= density x volume

So mass of water= density of water x volume
