Calculate the qsp or ksp, as indicated, and determine whether a precipitate will form when each of the following mixtures is prepared. (you may assume temperature is held constant, volumes are additive, and that the initial solutions, prior to mixing, are unsaturated.) (a) 25.30 ml 1.48 ✕ 10−4 m cacl2 is mixed with 25.16 ml 3.02 ✕ 10−3 m naf. (ksp for caf2

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
