Q1.Why NaCl give s a white precipitate with AgNO³ solution but CCl⁴ does not? Ans. NaCl is an  ionic conpound and hence gives Cl‐ions in the solution which combine with Ag+ ions given by AgNO³ to fom a white precipitate of AgCl but CCl⁴ is a covalent compound and does not give Cl‐ions . Q2.Why reaction between NaCl and AgNO³  is very fast but reaction between H² and Cl² is slow? Ans. NaCl and AgNO³ are ionic compounds, In solution, NaCl gives Na+ and Cl_ ions and AgNO³, gives Ag+ and NO‐³ions. The oppositely charged Ag+and Cl+ ions combine immediately. The reaction betwecn H2 and Cl2 involves breaking of covalent bonds which requires energy.
