Chapter 15, Problem 99E

Interpretation Introduction

Interpretation:

The addition of ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}$ to the tap water will lead to the precipitation of ${\text{CaSO}}_{\text{4}}$ or not, is to be determined.

Concept introduction:

If the ionic product value exceeds the solubility product constant value $\left(K_{sp}\right)$ then precipitation will occur.

Concentration can be defined as the number of moles of solute dissolved in $1L$ of solution.

Unit of concentration is $\text{mol/L or M}$.

The relation between grams and milligrams is:

$1\text{ g }=\text{ 1000 mg}$

The relation between liters and milliliters is:

$\text{1 L}=\text{1000 ml}$
