Chemistry
1 answer:
Tanzania [10]3 years ago
5 0

Answer:Calcium hydroxide is a polar compound. 2. Carbonates are insoluble in water unless it is combined with NH4+ or any group 1A ion. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed, or slaked with water.Ca(OH)2 is an ionic compound, in which Ca is the cation and OH is the anion. Ca (calcium) has a charge of 2+, since it is in group 2 on the periodic table.

Explanation: hope this helps and have a great night

If the a of a monoprotic weak acid is 2. 6×10−6, what is the ph of a 0. 33 m solution of this acid?
yawa3891 [41]

The pH of the monoprotic weak acid is 2.79.

<h3>What are weak acids?</h3>

The weak acids are the acids that do not fully dissociate into ions in the solution. Strong acids fully dissociate into ions.

The chemical reaction is HA(aq) ⇄ A⁻(aq) + H⁺(aq).

c (monoprotic acid) = 0.33 M.

Ka = 1.2·10⁻⁶

[A⁻] = [H⁺] = x

[HA] = 0.33 M - x

Ka = [A⁻]·[H⁺] / [HA]

2. 6 × 10⁻⁶ = x² / (0.33 M - x)

Solve quadratic equation: [H⁺] = 0.000524 M.

pH = -log[H⁺]

pH = -log(0.000524 M)

pH = 2.79

Thus,  the pH of the monoprotic weak acid is 2.79
