do not write outside the box this question is about test tube reactions of some ions in aqueous solution for each reaction in parts a to d state the colour of the original solution state what you would observe after the named reagent has been added to the solution in each case write an equation for the reaction that occurs a an excess of dilute sulfuric acid is added to a solution containing cro ions colour of original solution observation after an excess of reagent has been added equation marks b sodium hydroxide solution is added to a solution containing fe h o ions colour of original solution observation after reagent has been added equation marks c an excess of ammonia solution is added to a solution containing cu h o ions colour of original solution observation after an excess of reagent has been added equation marks wmp jan chem d sodium carbonate solution is added to a solution containing al h o ions do not write outside the box colour of original solution observations after reagent has been added equation marks turn over for the next question turn over wmp jan chem
