What is a flame test?
holding a hydrochloride acid dipped metal ion over a flame and seeing what colour the flame goes
Lithium goes crimson, sodium goes yellow, potassium goes lilac, calcium goes orangish-red and copper goes green
What is a precipitate?
an insoluble solid formed by a reaction taking place in a solution
Calcium chloride + sodium hydroxide ➡️ calcium hydroxide + sodium chloride
How are aluminium ions distinguished from calcium & magnesium ions in a reaction with sodium hydroxide?
aluminium dissolves
