How can you recognize an alcohol?

gavmur [86]

Answer:

O D. It has an -OH group attached to the end of the molecule.

Explanation:

Some alcohols have hydroxyl group (OH) attached to the end of a molecule and some have it attached as a branch on the molecule

${ \rm{R - OH \: : \: primary \: alcohol \: (1 \degree)}} \\ \\ { \rm{R -(OH) - R {}^{i} \: : secondary \: alcohol \: (2 \degree)}} \\ \\ { \rm{R - R {}^{i} (OH) - R {}^{ii} \: : tertiary \: alcohol \: (3 \degree)}}$

R is aryl or alkyl group
OH is hydroxyl group

Question 6 The mineral barite, (BaSO.) has a ke of 1.1 x 10" at 25°C. Calculate the solubility of barium sulfate in water, in: 6

Sav [38]

Explanation:

(6.1). The reaction equation will be as follows.

$BaSO_{4}(s) \rightleftharpoons Ba^{2+}(aq) + SO^{2-}_{4}(aq)$

Assuming the value of $K_{sp}$ as $1.1 \times 10^{-10}$ and let the solubility of each specie involved in this reaction is "s". The expression for $K_{sp}$ will be as follows.

$K_{sp} = [Ba^{2+}][SO^{-}_{2}]$ (Solids are nor considered)

= $s \times s$

s = $\sqrt{K_{sp}}$

= $\sqrt{1.1 \times 10^{-10}}$

= $1.05 \times 10^{-5}$

Therefore, solubility of barium sulfate in water is $1.05 \times 10^{-5}$ .

(6.2). As the molar mass of $BaSO_{4}$ is 233.38 g/mol

Therefore, the solubility is g/L will be calculated as follows.

$233.38 g/mol \times 1.05 \times 10^{-5}$

= $2.45 \times 10^{-3} g/L$

Therefore, solubility of barium sulfate in grams per liter is $2.45 \times 10^{-3} g/L$ .
