I have heard that aqua regia is a mixture of two monovalent acids (HNO₃ & HCl) in the ratio 1:3, what happens if it is neutralized by a mixture of two monovalent alkalis in the ratio of 1:3, which are both preferably metal hydroxides?

Question:

% Analyte = weight of Analyte/weight of sample × G.F ×100/1

G.F is the gravimetric factor = substance sought / substance known.

Calculations

1. Calculate the % sodium in a 0.721g detergent sample final Field is 0.320g NaP2O4.

2.A 0.2025 g sample consisting of only BaCl2 and KCl required 20.25 mL of 0.1200 M AgNO 3 solution for the quantitative precipitation of chloride.

Calculate the %K in the sample
