The molar solubility of Pbl_(2) in 0.2M Pb(NO_(3))_(2) solution in terms of solubility product, K_(sp)
If the solubility of Ca_(3)(PO_(4))_(2) in water is 'X' mol L_(-1) , its solubility product in mol^(5)L^(-5) is
K_(sp) of M(OH)_(x) , is 27 xx 10^(-12) and its solubility in water is 10^(-3) mol litre^(-1) . Find the value of X
M(OH)_x " has " a K_(sp) " of " 4 xx 10 ^(-9) and its solubility is 10^(-3) M. The value of x is :
The shape of PO_(4)^(3-) ion is
If 3.1gm Phospherous is present in a sample of Ca_(3)(PO_(4))_(2) the what is the weight of oxygen in the sample?
i) H_3PO_(4(aq)) iff H^ _(aq)+ H_2PO_(4(aq))^- ii) H_2PO_(4(aq))^- iff H^ +(aq)+ H_2PO_(4(aq))^(2-) . iii) H_2PO_(4(aq))^(2-) iff H^ +(aq)+ PO_(4(aq))^(3-) . The equilibrium constantsfor the above reactions at a certain temperature are K_1, K_2 and K_3 respectively. The equilibrium constant for the reaction. H_3PO_4(aq) iff 3H^ +(aq)+ PO_(4(aq))^(3-) in terms K_1, K_2 and K_3 is
