Q.

For the chemical reaction

the amount of  at equilibrium is affected by

Q.

 dissociates  When the initial pressure of  is 600 mm Hg, the total equilibrium pressure is 800 mm Hg. Calculate  for the reaction. Assuming that the volume of the system remains unchanged

Q. The solubility product of A2So4 is 8 into 10^-8.The concentration of A^+ ion in saturated solution is?

A2SO4 - 2A+ + So4 2-
x - x =0 2x x
8*10-8 = (2x)2 * x
find the value of x from here , concentration will be 2x

Q. What is autoprotolysies?
