WebTest for Carbonates. Carbonates all contain the carbonate ion, CO 32-. The test for this ion involves adding dilute acid and testing the gas released. If a carbonate compound is present then effervescence should be seen and the gas produced is CO 2 which forms a white precipitate of calcium carbonate when bubbled through limewater: CO32- (aq ...

Web29 mei 2024 · Question 10. Question. Metallic bonding is made of positive ions that are held together by a “sea of [blank_start]delocalised [blank_end] electrons” from the outer shells of metal atoms. The strong [blank_start]electrostatic [blank_end] forces between the ions and electrons mean metals have very high melting points. WebFor ionic compounds you have to balance the charge of each part by multiplying each ion until the sum of the charges = 0; Example: what is the formula of aluminium sulfate? Write out the formulae of each ion, including their charges; Al 3+ SO 4 2-Balance the charges by multiplying them out: Al 3+ x 2 = +6 and SO 4 2- x 3 = -6; so +6 – 6 = 0
