mL of xx molar hydrochloric acid is mixed with \mathrm{V}_2mLV2mL of $$$$\gamma$$ molar sodium hydroxide. Arrange the following steps in correct sequence for calculation of $$\mathrm{pH}$$ of the mixture. $$\left(y\ \textgreater \ x\right.$ and $\left.V_{1}\ \textgreater \ V_{2}\right)$$ (1) Calculation of the number of equivalents of acid and base. (2) Calculation of the total volume of mixture. (3) Calculation of the normality of acid and base. (4) Calculation of the net OH - ion

Answer:
For calculation of pH of the acid base salt mixture need to follow following steps .
(c) Calculation of the normality of acid and base
(a) Calculation of the number of equivalents of acid and base
(number of moles = number of equivalents for HCl and NaOH)
(b) Calculation of the total volume of mixture
(d) Calculation of the net OH
−
ion concentration
(f) Dividing K
w
by OH
−
ion concentration
(e) Taking the negative logarithm of H
+
ion concentration
