Question

calcium hydroxide conduct electricity or not

Answer 1

Answer:  YES

Explanation:

calcium hydroxide is not the most soluble salt, but it should be more than plenty for conducting electricity with a relatively low resistance. The solution is even used for the well known reaction showing CO2 ('lime water') so it's definitely not completely insoluble.

Answer 2

$\huge\underline{\underline{\mathfrak \red{Answer}}}$

Its density of 1.55 g/cm3 is the lowest in its group. Calcium is harder than lead but can be cut with a knife with effort. While calcium is a poorer conductor of electricity than copper or aluminium by volume, it is a better conductor by mass than both due to its very low density
