A) 0.15
B) 0.51
C) 0.78
D) 1.56
Correct Answer: D
Solution :
Mole of \[{{H}_{2}}S{{O}_{4}}\]in \[50\,mL\]stock solution \[=50\times 1.78\times \frac{86}{100}\times \frac{1}{98}=0.78\] Since, 50 mL of the above solution is diluted to 1.01. Molarity of\[{{H}_{2}}S{{O}_{4}}\] in dilute solution = 0.78M \[[{{H}^{+}}]=2\times 0.78\] \[=1.56\,M\]You need to login to perform this action.
