Answer:

Explanation:

Aqueous solution of copper sulphate

is acidic in nature, as when copper sulphate on dissolving with water, following chemical reaction takes place :

CuSO4 + 2 H2O ====> Cu(OH)2 + H2 SO4

As we can see, copper hydroxide and sulphuric acid is generated in this chemical reaction.Copper hydroxide is a weak base whereas sulphuric acid is a very strong acid which results into increase in acidity of the solution.

Thus, the aqueous solution of copper sulphate is acidic in nature.

Calculate the molality of a solution that contains 51.2 g of naphthalene, C10H8, in 500 mL of carbon tetrachloride. The density

PtichkaEL [24]

<u>Answer:</u> The molality of naphthalene solution is 0.499 m

<u>Explanation:</u>

Density is defined as the ratio of mass and volume of a substance.

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$ ......(1)

Given values:

Volume of carbon tetrachloride = 500 mL

Density of carbon tetrachloride = 1.60 g/mL

Putting values in equation 1, we get:

$\text{Mass of carbon tetrachloride}=(1.60g/mL\times 500mL)=800g$

Molality is defined as the amount of solute expressed in the number of moles present per kilogram of solvent. The units of molarity are mol/kg. The formula used to calculate molarity:

$\text{Molality of solution}=\frac{\text{Given mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Mass of solvent (in g)}}$ .....(2)
