Interpretation:
Two gases NH3 and phosphine gas, PH3 are effusing through a small pinhole at same temperature. 1.73 ×10-3 mol NH3 gas takes time of 11.2 second for effusing. Time taken by PH3 with same amount that is 1.73 ×10-3 mol is to be determined.
Concept introduction:
Rate of effusion of is a process of escaping of molecules from high pressure to lower pressure at particular rate. Itcan be calculated by dividing moles of gas by time of effusion. Given as-
Where n = moles of gas
t = effusion time
Rate of effusion is also inversely proportional to the square root of the molar mass of atom. Ratio of rate of effusion is given as-

(b) When do you need to perform back titration? (c) Ni2+ can be analyzed by a back titration using standard Zn2+ at pH 5.5 with xylenol orange indicator. A solution containing 25.00 mL of Ni2+ in dilute HCl is treated with 25.00 mL of 0.05283 M Na2EDTA. The solution is neutralized with NaOH, and the pH is adjusted to 5.5 with acetate buffer. The solution turns yellow when a few drops of indicator are added. Titration with 0.02299 M Zn2+ requires 17.61 mL to reach the red end point.
