Which Double Replacement Reactions Will Form A Precipitate Or A Gas

Decent Essays
The purpose of this experiment was to determine which double displacement reactions will form a precipitate or a gas. A double displacement reaction is a type of chemical reaction where two compounds react with each other and the positive ions and the negative ions switch places, forming a new compound. A double displacement reaction usually occurs between two compounds that are in an aqueous solution. The general equation for a double displacement reaction is AX+BY= AY+BX(Clancy 171). In this equation A and B are positive charged ions, and X and Y are negative charged ions. There are three types of double displacement reactions; a reaction that forms a solid, a reaction that forms a gas and a reaction that forms water.(Clancy 172) During
