In a titration, the solution changes color at the
end point
equivalence point
What is the equivalence point of a titration?
Where the amount of acid and base are balanced according to the equation
Where there is no base
At the end
Zn(OH)2 + HNO3 ---> H2O + Zn(NO3)2

What is the equilibrium expression for the solubility product (Ksp) of the following salt :
MgCO3
Ksp = [Mg2+] [CO3-]
Ksp = [Mg2+] [CO32-]
Ksp = [Mg2+]2 [CO32-]
Ksp = [Mg2+] [CO32-]2
What is the equilibrium expression for the solubility product (Ksp) of the following salt :
Al(OH)3
Ksp = [Al+] [OH-]3
Ksp = [Al2+] [OH-]3
Ksp = [Al+]3 [OH3-]
Ksp = [Al3+] [OH-]3
