Calculate the pOH for the following:

Sergeeva-Olga [200]

The pOH refers to the negative logarithm of the hydroxide concentration.

The term pOH refers to the negative logarithm of the hydroxide concentration. Now we know that there is a relation that states that;

[H+] [OH-] = 1 * 10^-14

We shall now apply this relation in each case as follows;

[OH-] = 1 * 10^-14/1 x 10-12

[OH-] = 1 * 10^-2

pOH = 2

2. pOH = -log( 1 x 10-6 M) = 6

3. [OH-] = 1 * 10^-14/ 1 x 10-1

[OH-] = 1 * 10^-13

pOH = 13

4. [OH-] = 1 * 10^-14/ 1 x 10-4

[OH-] = 1 * 10^-10

pOH = 10

5. pOH = -log( 1 x 10-7) = 7

Elden [556K]

Answer:

When copper(II) chloride and sodium carbonate solutions are combined, solid copper(II) carbonate precipitates, leaving a solution of sodium chloride. Write the conventional equation, total ionic equation, and net ionic equation for this reaction.

Explanation:

The word equation for the reaction is:

Copper (II) chloride(aq) + sodium carbonate (aq) ->sodium chloride (aq) + copper carbonate(s)

The balanced chemical equation of the reaction is:

$CuCl_2(aq)+Na_2CO_3(aq)->2NaCl(aq)+CuCO_3(s)$

The complete ionic equation is:

$Cu^2+(aq)+2Cl^-(aq)+2Na^+(aq)+CO_3^2^-(aq)->2Cl^-(aq)+2Na^+(aq)+CuCO_3(s)\\$

The net ionic equation is obtained from the complete ionic equation after removing the spectator ions:

$Cu^2^+(aq)+CO_3^2^-(aq)->CuCO_3(s)$
