Chapter 9, Problem 9.98QP

Interpretation Introduction

Interpretation:

The mass percentage of $\text{Ba}$ in the unknown original compound should be calculated.

Concept introduction:

Precipitation reaction:

When two solutions are mixed together and if an insoluble compound settles down in the solution, which is known as precipitate, then the reaction is known as a precipitation reaction.

The mass of the precipitate depends on the reactant masses.

Mole:

Mole of the compound is given by ratio between mass of the analyte and molar mass of the compound.

$\text{Mole}\text{=}\frac{\text{Mass}}{\text{Molar}\text{mass}}$

Mass:

The mass of solute present in the solution is given by multiplication of mole and molar mass of the solute.

$\text{Mass}\text{=}\text{Mole}\text{×}\text{Molar}\text{mass}$
