Answer:
100x less acidic
Step-by-step explanation:
pOH is the inverse of pH, which is a measure of the acidity or basicity of a solution. The lower the pH of a solution, the more acidic it is, and the higher the pOH, the less acidic it is.
To determine how many times more acidic a solution with a pOH of 12 is compared to a solution with a pOH of 10, we can use the formula:
pH1 / pH2 = 10^(pOH1 - pOH2)
In this case, we are given that the pOH of the first solution is 12 and the pOH of the second solution is 10. We can plug these values into the formula to calculate the ratio of acidity:
pH1 / pH2 = 10^(12 - 10)
= 10^2
= 100
Therefore, a solution with a pOH of 12 is 100 times less acidic than a solution with a pOH of 10.
