Hi can someone please help me with this. Thank you!!

Question

calculate the concentration of the hydrogen ion/hydroxide ion in

the samples below by its pOH level. Identify if the solution is acidic, basic, or neutral.

1. Calculate the hydroxide

ion concentration of a

solution with a pOH

level of 3.80.

2. Calculate the hydroxide

ion concentration if a

solution has a pOH

reading of 12.24.

3.Calculate the

hydroxide ion

concentration of a

solution with a pH

reading of 14.

4.If a solution has a pOH

reading of 0.9, what is

the hydroxide ion

concentration?

5. If a solution has a

11.50 pOH reading,

what is the hydroxide

ion concentration?

Answer 1

1. Calculate the hydroxide

ion concentration of a

solution with a pOH

level of 3.80.

[OH^-]=10^-pOH=10^-3.80=0.000156 M

2. Do the same thing shown above, [OH^-]=10^-pOH

3.Calculate the

hydroxide ion

concentration of a

solution with a pH

reading of 14.

pH+pOH=14

14+pOH=14

pOH=0

[OH^-]=10^-pOH=10⁰=1

4.If a solution has a pOH

reading of 0.9, what is

the hydroxide ion

concentration?

[OH^-]=10^-pOH

5. If a solution has a

11.50 pOH reading,

what is the hydroxide

ion concentration?

[OH^-]=10^-pOH
