Answer:
D. 1.0 x 10-8.43
Explanation:
The pH is an unit of concentration in chemistry used to determine the acidity -or basicity- of a particular solution. Is used in quality control to determine the security of a product for consumers.
The equation is:
pH = -log [H₃O⁺]
As pH = 8.43:
8.43 = -log [H₃O⁺]
10^-8.43 = [H₃O⁺]
1.0x10 -8.43 = [H₃O⁺]
Right option is:
<h3>D. 1.0 x 10-8.43
</h3>
