Calcium reacts with water. this reaction is represented by the balanced equation below. the aqueous product of this reaction can be heated to evaporate the water, leaving a white solid, ca(oh)2(s).
ca(s) + h2o(l) ==> ca(oh)2(aq) + h2(g)
compare the electrical conductivity of the aqueous product in the reaction to the electrical conductivity of the white solid that remains after the water is evaporated from the solution.
write the chemical name of the base produced in the reaction.
state one change in reaction conditions that will increase the rate of the reaction.
