Question

ph of hcl is 3 then the ph of NaOH solution having same molar concentration is​

Answer 1

Answer:

11

Explanation:

pH of HCl = 3

[H+] = 10^(-3)

It's given that molar concentration of HCl and NaOH is same. So, molar of concentration of OH- ion from NaOH is

[OH-] = 10^(-3)

pOH = -log[10^-3] = 3

pH = 14 - 3 = 11

Answer 2

Answer:11

Explanation:

PH=3,then concentration of [H+] ion is 10^-3. Molarity of HCl is also 10^-3. Therefore given that concentrations are same. Molarity of NaOH is also 10^-3. Normality = molarity * n factor . Here n factor in one ( in NaOH).

We know that pOH =-log(normality of base), -log(10^-3)=3

pOH =3 then pH of NaOH is 14-3= 11
