% hydrolysis of 0.1M CH_(3)COONH_(4), when K_(a)(CH_(3)COOH)=K_(b)(NH_(4)OH)=1.8xx10^(-5) is:
Which has higher pH value: 1M NaOH(aq) or 1M HCl(aq)?
Out of internal energy (I), boiling point (II), pH (III) and E.M.F. of the cell (IV) intensive properties are :
one litre of an aqueous solution contains 0.15 mole of CH_(3)COOH(pK_(a) =4.8)) and 0.15 mole of CH_(3) COONa. After the addition of 0.05 mole of solid NaOH to this solution, the pH will be :
At 25^(@)C, will a precipitate of Mg (OH)_(2) from when a 0.0001 M solution of Mg(NO_(3))_(2) is adjusted to a pH of 9.0 ? At what minimum value of pH will precipition start ? ["Given" : K_(sp)(Mg(OH)_(2))=10^(-11)M^(3)]
pH of 0.01 M aq. Solution of HA is 4. Find the value of pK_(a) of HA at 25^(@)C.
An aqueous solution at room temperature contains 0.1 M NH_(4)Cl and 0.01M NH_(4)OH (pK_(b)=5), the pH of the solution is :
