A drop of a Solution (Volume = 0.05 ml) contains 6 x 10^-7 moles of hydrogen ion concentration. If the rate of disappearance of the ion is 6 x 10^5 mol/L s, and if it takes x x 10^-8 seconds for the ion to disappear, Find the value of x. (Type: Sitter)
Answer: Vol. = 0.05 ml = 5 x 10^-5 L
Concentration of Hydrogen ion = (6 x 10^-7)/(5 x 10^-5)
= (6 x 10^-2)/5 mol / L
Rate = Conc. / Time
6 x 10^5 = (6 x 10^-2) / (5 x x x 10^-8)
On solving this equation we get x = 2
Hence the value of x is 2
