CHEMISTRY
Following solutions were prepared by mixing different volumes of NaOH and HCI of different concentration:
A
60mL 
HCI+40mL 
NaOH d
HCI+40mL NaOH d
B
55mL 
HCI + 45mL 
NaOh a
HCI + 45mL NaOh a
C
75mL 
HCI + 25mL 
NaOH b
HCI + 25mL NaOH b
D
100 mL 
HCI + 100mL 
NaOH pH of which one of them will be equal to 1? c
HCI + 100mL NaOH pH of which one of them will be equal to 1? c
Text Solution
Verified by ExpertsThe correct answer is:
Total volume = 75mL 
HCI + 25mL 
NaOH = 100ml
25 mL 
NaOH will neutralise25 ml 
HCI
Reamaiming HCI = 75 -25 =20 ml
