Answer:
The pH of the solution is 10,46.
Explanation:
The pH gives us an idea of the acidity or basicity of a solution. More precisely, it indicates the concentration of H30 + ions present in said solution. The pH scale ranges from 0 to 14: from 0 to 7 corresponds to acid solutions, 7 neutral solutions and between 7 and 14 basic solutions. It is calculated as:
pH = -log (H30 +)
pH= -log (3.5*10^-11)
<em>pH= 10,46</em>
J the same idea that but I’m in gonna right now I’m going out of my work class tomorrow and I will text
