CADMIUM SOLUBILITY AND pH Cadmium is a toxic metal. It can be removed from water by chemical precipitation of solid cadmium hydr

Serga [27]

Explanation:

It is known that,

Molar mass of Cd = 112.41 g/mol

Standard concentration of Cd = 0.005 mg/L = $0.005 \times 10^{-3}$ g/L

Hence, we will calculate the molarity as follows.

Molarity = $\frac{0.005 \times 10^{-3}}{112.41} mol/L$

= $4.45 \times 10^{-8}$ M

Equation for the reaction is as follows.

$Cd(OH)_{2} \rightleftharpoons Cd^{2+} + 2OH^{-}$

$K_{sp} = [Cd^{2+}][OH^{-}]^{2}]$

$2 \times 10^{-34} = 4.45 \times 10^{-8} \times [OH^{-}]^{2}$

$[OH^{-}] = 6.7 \times 10^{-4}$ M

Also,

$[H^{+}] = \frac{10^{-14}}{[OH^{-}]}$

= $\frac{10^{-14}}{6.7 \times 10^{-4}}$

= $1.49 \times 10^{-11} M$

Relation between pH and concentration of hydrogen ions is as follows.

pH = $-log [H^{+}]$

= $-log (1.49 \times 10^{-11} M)$

= 10.82

Thus, we can conclude that a minimum pH of 10.82 is necessary to reduce the dissolved cadmium ion concentration to the standard.

An acid has a molarity of 0.01 M. What does the 0.01 M refer to?

bulgar [2K]

Answer : The correct option is, The concentration of the acid.

Explanation :

Molarity : Molarity is defined as the moles of solute present in one liter of the solution. Or it is defined as the concentration of solute present in one liter of solution.

The unit of molarity is, (M) i.e, mole/liter. It is also known as molar concentration.

Molarity of 0.01 M means, 0.01 concentration of the acid present in the solution.

Therefore, the 0.01 M refer to the concentration of the acid.
