Answer:
5.62 * 10^-13 moles per liter
Explanation:
The pH of a solution is the negative logarithm to base 10 of the concentration of hydrogen ions. What we simply do here is to input the information in the question into the equation:
pH=−log10[H⁺]
Here we know the pH but we do not know the concentration of the hydrogen ions.
12.25 = -log [H+]
log[H+] = -12.25
[H+] = 10^-12.25
[H+] = 5.62 * 10^-13 moles per liter
Answer: It has a charge of -2 because it has 2 more electrons than protons meaning it has a negative charge of 2 which is -2. Neutrons don't effect charge.
( +1 +1 -1 -1 -1 -1) = -2
Each proton has a charge of +1 and each electron has -1.
2(1) - 4(1) = -2
