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.
C Give the formula compound A.

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
