Question

Solutions prepared by mixing different volumes of Na OH and HCl of different concentrations , pH of which one of them will be equal to 1 ?

Answer 1

Following solutions were prepared by mixing different volumes of NaOH and HCI of different concentrations :

:a. 60 mL —M/10 HC1 + 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

c. 75 mL M/5 HCl + 25 mL M/5 NaOH

d. 100 mI—M/10 HCl + 100 mL —M/

10 NaOH✔✔

☣4th one is correct it is equal to1☣
