Answer 1

Part E To find the [H30*] Given that [OH-] = 3.6x10-10M K, -[07-(04] K, = water ionisation constant (1.0x10-14) K, =1.0*10-44 at 25°C K, =[0H-][H30*] [1,0*) - TOATE 3.6x10-10 [H,0*] = 1.0x10** = 2.7x10-M Hence the [H3O+]=2.7x10-M Part F To find the pH pH=-log[H,0*] = -log[2.7x109] = 4.56 This solution pHislessthan 7 so it is acidic solution
