A) 1.0
B) 3.0
C) 2.0
D) 4.5
Correct Answer: A
Solution :
The acid is called strong acid when it ionise upto great extent i.e. if its \[{{K}_{a}}\] value is large. We know that, \[p{{K}_{a}}=\log \frac{1}{{{K}_{a}}}\] Hence, larger the value of Ka, smaller will be the value of \[p{{K}_{a}}\]. Hence, low value of \[p{{K}_{a}}\]means that acid is strong.You need to login to perform this action.
