A sample of compound A was heated in a Bunsen flame and no flame colour. On addition of sodium
hydroxide solution to a solution of A, a white precipitate formed that did not re-dissolve when more sodium
hydroxide was added. When nitric acid was added to a solution of A, the mixture bubbled giving a gas that
turned limewater cloudy.
a Give the formula of the positive ion in A.
b Give the formula of the negative ion in A.

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
