Question

Net ionic equation for
SrCl2+2KOH=2KCl+Sr(OH)2

Answer 1

use a solubility table to determine which product is insoluble, and will make a precipitate. Then cancel out the spectators that don't form the precipitate.\[A^{(+)}B^{(-)}(aq) + C^{(+)}D^{(-)}(aq) \rightarrow A^{(+)}D^{(-)}(aq) + CB(s)\]\[C^{(+)}(aq) + B^{(-)}(aq) \rightarrow CB(s)\]
