**Question:**What mass of Na₂CrO₄ is required to precipitate all of the silver ions from 25.0 mL of a 0.200 M solution of AgNO₃?**Answer:**Mass = [ ] g---**Explanation:**This question involves stoichiometry and precipitation reactions. It asks for the mass of sodium chromate (Na₂CrO₄) needed to completely precipitate all silver ions from a given volume and concentration of silver nitrate (AgNO₃) solution. To solve it, one must understand the chemical reaction between silver nitrate and sodium chromate leading to the formation of silver chromate (Ag₂CrO₄) as a precipitate.

Molarity of AgNO3 = 0.200 M Volume of AgNO3 solution = 25.0 mL = (25.0 / 1000 ) L = 0.025 L We need…

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
