Describe the properties of dots with regard to their reactions with metals, bases and atomic number 6ates. Acids taste sour, conducts electricity and has a pH begin than 7. Therefore, it gamblings red if universal indicator is added and deflects blue litmus test radical red. Strong bitters with a pH of 1 or 2, crack more hydrogen ions and be truly corrosive slice weak acids with a pH of 5 or 6 contain less hydrogen ions therefore, they are not that corrosive. When an acid is added with a metal, salt and hydrogen are produced. Hydrogen, which quickly bubbles absent during the reaction is displaced by the metal added. The bubbles get out stop when wholly the acid has been used up. When an acid is added with a base, salt and water system are produced. When an acid is added with a carbonate, salt, water and carbon dioxide are produced. 2. Explain the test for carbonate ions using profane hydrochloric acid and limewater. carbonate ions can be tested by adding dilute hydro chloric acid and putting the presumptuousness off gas into limewater. If carbonate ions are present, limewater will turn milky or nebular because when an acid and carbonate react, it gives of carbon dioxide, which turns limewater cloudy.

For example:Sodium Carbonate + Hydrochloric acid ? Sodium Chloride + pee + Carbon DioxideNa2CO3 + 2 HCl ? 2 NaCl + H2O + carbon dioxideThe quiet carbon dioxide will therefore turn limewater cloudy. Limewater is a viridity name for saturated atomic number 20 hydroxide solution, Ca(OH)2. When carbon dioxide is added to limewater, water and calcium carbonate (chalk) are produced . In limewater, if carbon dioxide are presen! t, a white precipitation of calcium carbonate (chalk) will form. Limewater + Carbon dioxide ? Calcium Carbonate + WaterCa(OH)2 + carbonic acid gas ? CaCO3 + H2O3. Describe how solutions are acidic, alkaline or neutral... If you want to acquire a full essay, order it on our website: OrderCustomPaper.com
