During a practical class, the laboratory demonstrator gave a student a 0.090M solution of unknown weak base. The student measured the pH to be 10.7. The temperature inside the laboratory was 25°C. Calculate the [H*] and [OH¯] of the solution. Write out the generic equation and the equilibrium expression for the ionisation reaction of a weak base in water.(b) (c)Calculate the Kp and pKp of the weak base. (d)Looking at the Kp values given in Appendix 2, what was the weak base in the solution?
