Heya mate✌❤☺

Explanation:

✏When caustic soda(NaoH) is added to lead nitrate, lead hydroxide and sodium nitrate are formed

●2NaoH+pb(NO3)2➡Pb(OH)2+2nano3

✏When caustic soda is added in excess white gelatinous precipitate(sodium plumbite) is formed which is soluble in excess..

●Pb(OH)2+2NaoH➡Na2pbo2(sodium plumbite, soluble salt)+2H2O.....
