Answer:
pH = 7
Explanation:
pH is defined as -log [H⁺]. In a solution of pH 5:
pH = -log [H⁺]
10^(-5) = [H⁺]
1x10⁻⁵M = [H⁺].
Then, this solution is diluted from 10mL to 1000mL (990mL of water + 10mL of the original solution). That means the solution is diluted:
1000mL / 10mL / 100 times.
If [H⁺] before dilution was 1x10⁻⁵M, after dilution will be:
1x10⁻⁵M / 100 = 1x10⁻⁷M
And pH:
pH = -log [H⁺]
pH = -log 1x10⁻⁷M
<h3>pH = 7</h3>
Answer:
Filtration
Explanation:
Evaporation could work, but it would take too long and might be harmful to the environment. This is not the answer.
Distillation is used to purify a substance. It is generally only used when separating two liquids. This is not the answer.
Filtration is where you would pour the liquid through a filter and collect the solid. This is the answer.
Chromatography is technique that is used to test whether something is pure. You would not be able to separate the two substances using this technique. This is not the answer.
