Types Of Reactions

Question 1

Precipitation

Answer 1

A solid forms from aqueous ions

Question 2

A solid forms from aqueous ions

Answer 2

Precipitation

Question 3

Complex ion

Answer 3

Two step reaction where, due to the cations large size, the cation can join with more than two ions in a species. The first reaction will result in a precipitate, but upon addition of more anion the precipitate will disappear.

Question 4

Two step reaction where, due to the cations large size, the cation can join with more than two ions in a species. The first reaction will result in a precipitate, but upon addition of more anion the precipitate will disappear.

Answer 4

Complex ion

Question 5

Redox

Answer 5

Formal charges of elements change after a reaction, usually single replacement. A colour change with no precipitate is observed.

Question 6

Formal charges of elements change after a reaction, usually single replacement. A colour change with no precipitate is observed.

Answer 6

Redox

Question 7

Acid-base

Answer 7

A neutral compound is formed from two ions, heat is released in the reaction.

Question 8

A neutral compound is formed from two ions, heat is released in the reaction.

Answer 8

Acid-base
