What are pH and Salts?

1 answer:

6 0

Answer:

The pH of a salt solution is determined by the relative strength of its conjugated acid-base pair. Salts can be acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl).

What is the molarity of a solution of 10% by mass cadmium sulfate, CdSO4 (molar mass = 208.46 g/mol) by mass? The density of the

Gekata [30.6K]

Answer:

a. 0.528 M ..

Explanation:

Hello!

In this case, since the given by-mass percent can be written as:

$\frac{10gCdSO_4}{100g\ sol}$

By using the density and molar mass of the solute, cadmium sulfate, we can compute the molarity, by also making sure we convert from mL to L of solution:

$M=\frac{10gCdSO_4}{100g\ sol}*\frac{1molCdSO_4}{208.46gCdSO_4} *\frac{1.10g\ sol}{1mL\ sol} *\frac{1000mL\ sol}{1L\ sol} \\\\M=0.528M$

Thereby, the answer is a. 0.528 M .

Best regards.
