M(OH)2 gives M+(ion) + 2 (OH)- ions. So concentration of M+ ion is half that of OH- ions. To calculate the concentration of OH minus ions we need pOH value which is equal to {14 - pH}. In this question pH is 13 therefore pOH = 1. Concentration of OH ions is given by = 10^ (-pOH). ...

In this question pH is 13 therefore pOH = 1. Concentration of OH ions is given by [OH] = 10^ (-pOH). = 10^-1 =0.1 M (here M is molarity, mol/l) To calculate concentration of metal ion namely [M] is half of the concentration of OH ion =(0.1)/2 =0.05 M once we have concentration of these let us now calculate the Ksp value. Ksp for this = [M] * [OH]^2 = 0.05 * (0.1)^2 =0.0005 = 5* !0^(-4) units will be M^3 read less

pH value = 13 , pOH = 14-13 = 1 , = 10-1 = 0.1 , = 0.1/2 = 0.05 , Ksp = 2 = (0.05)2(0.1) Ksp = 0.0025 x 0.1 = 2.5x10-4

IIT/BITSAT Decoded !!

Hi K.kamal Here is the solution to your problem: M(OH)2 ---> M2+ + 2OH- (1) Ksp = X^2 (2) Now concentration of OH- can be calculated as pOH+PH =14 at 25C taken as standard. therefore POH=1 { ph=13 given } hence OH- =10^-1 Now conc. of M2+ will be half...

Hi K.kamal Here is the solution to your problem: M(OH)2 ---> M2+ + 2OH- (1) Ksp = [M2+]X[OH-]^2 (2) Now concentration of OH- can be calculated as pOH+PH =14 at 25C taken as standard. therefore POH=1 { ph=13 given } hence OH- =10^-1 Now conc. of M2+ will be half the conc. of OH- at equib. as it is clear from above equation(1) therefore putting values in (2) Ksp= (0.5x10^-1)x(10^-1)^2 = 0.5x10^-3 mol^3litre^-3 read less

MATH PHY CHEM TEACHER ONLY SANT NAGAR BURARI

We know the Ksp and we know the solution is saturated. This information will be sufficient.we must first calculate the . To do this, we will use the Ksp expression and then, at the end, we will use acid base concepts to get the pH. Ksp are almost always given at 25.0 °C in reference sources
