Metallic tin in the presence of HCl is oxidized by `K_(2)Cr_(2)O_(7)` to stannic chloride, `SnCl_(4)` . What volume of deci-normal dichromate solution would be reduced by 1 g of tin.

Options

A. 168.49 mL
B. 175.49 mL
C. 170.50 mL
D. 162.38 mL

Answer

A

Explanation

`overset((+2))(SnCl_(2)) to overset((+4))(SnCl_(4))`
Equivalent wt. 2
No. of g. equivalents `= (1g)/(119//2g) = (2)/(119)`
` 0.1 xx V = 2 //119`
`V = 168.07` mL
