The statements regarding the compounds of sodium arei) The mixture of NaOH and CaO is used as decarboxylating agentii) aq. NaOH reacts with silicon to form water glass

→ NaOH + CaO mixture is called soda lime, and it is used for decarboxylation of carboxylic acid,and hence it is used for decarboxylation of carboxylic acid, and hence it is said to be decarboxylating agent→ silicon reacts with aq.NaOH to form sodium silicate [Na2SiO3] which is said to be water glass2NaOH + Si + H2O → Na2SiO3 + 2H22NaOH + SiO2 → Na2SiO3 + H2O
