#12

Front (Question)

sterioisomerism

Back (Answer)

same structural formula but a different arrangement of the atoms in space

#13

Front (Question)

what are the 2 types of stereoisomerism that complex ions can show?

Back (Answer)

• cis- trans isomerism - optical isomerism

#14

Front (Question)

precipitation reaction

Back (Answer)

occurs when 2 aqueous solutions containing ions react together to form an insoluble solid, called a precipitate
