Answer:
a
Explanation:
because titration by definition, is used to determine the concentration of one reactant in an aqueous solution, it requires a burette to accurately measure the volume of a solution and endpoints in acid-base titration can be determined by a colour indicator or a pH meter
It’s some apps that come in handy for this sorry if I didn’t help
If it is just a simple double-replacement reaction, then the balanced equation is simply:
Pb(ClO3)2(aq) + 2 NaI(aq) = PbI2 + 2 Na(ClO3)
However, if this is a precipitation reaction, we must identify which compound will precipitate (is insoluble), either NaClO3 or PbI2
NaClO3 is soluble, PbI2 is not. Only the lead cations and iodine anions will participate in the reaction.
thus, the balanced equation is: Pb^(2+) + 2I^(-) ==> PbI2
False the ability to conduct heat is a physical property
