precipitation reactions

Question 1

precipitation reaction definition

Answer 1

where two ionic solutions are mixed and an insoluble precipitate is formed.

Question 2

precipitation reaction general formula

Answer 2

AB + CD = AD + CB

Question 3

forming precipitates

Answer 3

atoms are exchanged between compounds. When soluble ionic compounds are mixed, the ions are swapped between the dissolved compounds and result in one compound forming a precipitate

Question 4

precipitate definition

Answer 4

solid that forms and sinks to the bottom of a solution

Question 5

aqueous

Answer 5

in water

Question 6

spectator ion

Answer 6

ion that does not take part in a chemical reaction. they remain unchanged and are present in the solution.

Question 7

solubility

Answer 7

how much a compound appears to dissolve

Question 8

forming word and formula equations

Answer 8

the last word/part from both compounds swap places with the other. MUST balance formula equations

Question 9

forming ionic equations

Answer 9

take only the precipitate and ions that formed it and write equation with only them. (spectator ions are left out.)

Question 10

why does a precipitate form

Answer 10

forms because the compound is insoluble, meaning the attraction between the ions is greater than the attraction between water molecules.
