Question

Following solutions were prepared by mixingdifferent volumes of NaOH and HCl ofdifferent concentrations :
a. 60 mL (M/10) HCl + 40 mL (M/10) NaOH
b. 55 mL (M/10) HCl + 45 mL (M/10) NaOH
c. 75 mL (M/5) HCl + 25 mL (M/5) NaOH
d. 100 mL (M/10) HCl + 100 mL (M/10) NaOH
pH of which one of them will be equal to 1?
(1) d
(2) a
(3) b
(4) c

Answer 1

$\bf\large\underline\purple{Answer:-}$

1) D is right.

Answer 2

HEY MATE

AS WE KNOW THAT PH SCALE IS INVERSELY PROPOTIONAL TO HYDROGEN ION CONCENTRATINON

SO THE CORRECT ANSWER IS

4(C)
