Determine the number of protons, neutrons & electrons of the following ions: Answer 1: The atomic number of a magnesium atom is 12 and the mass number is 24. Therefore the number of protons in a Mg2+ ion is also 12 – the number of protons does not change when an ion is formed. Answer 2: The atomic number of a fluorine atom is ...

WebThe test used for detecting acetate is Ferric Chloride. In this test, HCl is added to the test tube containing precipitate in which it just dissolved. The salt solution is then mixed with the resultant solution which contains acetate. This gives a red colour solution. To obtain red precipitate, water is added to this solution. Suggest Corrections.
