Based on the calculations, the solubility of mg(oh)₂ at a pH of 12.70 is equal to 3.4 × 10⁻⁵ M.
<u>Given the following data:</u>
- Ksp of mg(oh)₂ = 1.6 × 10⁻¹³
<h3>What is pH?</h3>
pH is an abbreviation for the power of hydrogen ions and it can be defined as a measure of the molar concentration of hydrogen ions that are present in a given solution. Thus, the power of hydrogen ions (pH) is generally used to identify or specify the acidity, neutrality, or basicity of any chemical solution.
First of al, we would write the properly balanced chemical equation for this chemical reaction:
Mathematically, the Ksp for the above chemical reaction is given by:
Ksp = [Mg²⁺][OH⁻]²
Ksp = [x][2x]²
1.6 × 10⁻¹³ = 4x³
x = ∛4 × 10⁻¹⁴
x = 3.4 × 10⁻⁵ M.

This is the correct sentence:
- My mom suggested keeping the surroundings clean and green.
It's correct to say keeping and not <em>keep</em> because you have to form the sentence using suggest + the verb with ing (keep + ing: keeping).
I was able to find the instructions to complete the exercise online: <em>Write sentences using suggest + V-ing or suggest + clause with should.</em>
