2. Acids such as HCI, HNOstep three are almost completely? onised and hence they have high Ka value i.e., Ka for HCI at 25°C is 2 x 10 6 .
cuatro. Acids with Ka value greater than ten are considered as strong acids and less than one considered as weak acids.
- HClO4, HCI, H2SO4 – are strong acids
- NH2 – , O 2- , H – – are strong bases
- HNO2, HF, CH3COOH are weak acids
Question 5. pH of a neutral solution is equal to 7.
