Answer is:
10−12
Explanation:
Kw = [H+][OH−]
Answer is:
KCN
Explanation:
Solution of KCN is basic. Therefore, concentration of [H+] will decrease on mixing it with acetic acid and thus pH will increase.
Answer is:
pH > 7
Explanation:
CH3NH2 is basic.
Answer is:
10−5
Explanation:
Ka = Cx2
Answer is:
Na2CO3
Explanation:
Na2CO3 is the most basic. The pH scale ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic). A pH meter is an instrument used to measure acidity or alkalinity of a solution - also know as pH.
