Concentrated aqueous sulphuric acid is 98% acid required to make one litre of 1.80 g `mL^(-1)`. Volume of acid required to make one litre of 0.1 M `H_(2)SO_(4)` solution is :
A. 16.65 mL
B. 22.90 mL
C. 11.10 mL
D. 5.55 mL
Correct Answer - 15.7 M
12.7 mL
Step I. Calculation of molarity of the acid solution.
`"Mass of solution"=100 g, "Density of solution "=1.787"gm L"^(-1)`
`"Volume of 100 g of solution"=("Mass")/("Density")=((100g))/((1.787"...
Correct Answer - 9.37 mL; 92.67 g
Step. Calculation of molarity of 95% `H_(2)SO_(4)` solution.
`"Mass of "H_(2)SO_(4)" in 100 g of solution"=95 g`
`"Density of solution"=1.85 mL^(-1)`
`"Volume of 100...
Correct Answer - a
Since `H_(3)PO_(3)` is dibasic, 0.1 M solution =- 0.2 N solution.
`underset(("Acid"))(N_(1)V_(1))=underset(("Base"))(N_(2)V_(2))`
`(0.2 N)xx20 mL)=(0.1N)xxV_(2)`
`V_(2)=((0.2N)xx(20mL))/((0.1N))=40 mL.`
Correct Answer - B
`Cu(M)+AgNO_(3)(N)`(queous colourless solution) `to` Resultant solution contains `Cu(NO_(3))_(2)` (blue solution) and `AgNO_(3)` (colourless solution)
Note: Here it is considered that complete `AgNO_(3)` is not utilized in the...
