CHEMICAL REACTIONS

1.    Write complete ionic and net ionic equations and identify spectator ions and type of reaction:

a.    AgNO3(aq) + KCl(aq) →AgCl(s) + KNO3(aq)

b.    CaS(aq) +CuCl2(aq) →CuS(s) +CaCl2(aq)

c.     Na2SO4(aq) +CaI2(aq) →CaSO4(s) +2NaI(aq)

2.    What is false about acids and bases:

Acids turn litmus blue                              bases turn litmus blue

Aids produce H+                                       Bases produce H+

Acids are sour to taste                             bases are bitter to taste

Acids are corrosive                                  bases are soapy in texture
