Answer: a) pH = 13.00 : basic
b) : basic
c) pOH = 5.00 : basic
d) : acidic
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.Neutral substances have pH of 7.
a) pH = 13.00
As pH is more than 7, the solution is basic.
b)
Putting in the values:
As pH is more than 7, the solution is basic.
c) pOH = 5.00
As pH is more than 7, the solution is basic.
d)
Putting in the values:
As pH is less than 7, the solution is acidic.
