Describe the properties of dots with regard to their reactions with metals, bases and changes. Acids taste sour, conducts electricity and has a pH begin than 7. Therefore, it gamblings red if universal indicator is added and grows blue litmus 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 lead 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 carbon paperate, 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 hydrochloric acid an d putting the given 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 + water supply + Carbon DioxideNa2CO3 + 2 HCl ? 2 NaCl + H2O + carbon dioxideThe gathered carbon dioxide will therefore turn limewater cloudy. Limewater is a parking lot name for saturated atomic number 20 hydroxide solution, Ca(OH)2. When carbon dioxide is added to limewater, water and atomic number 20 carbonate (chalk) are produced. In limewater, if carbon dioxide are present,! a white precipitation of calcium carbonate (chalk) will form. Limewater + Carbon dioxide ? Calcium Carbonate + WaterCa(OH)2 + carbon dioxide ? CaCO3 + H2O3. Describe how solutions are acidic, alkaline or neutral... If you want to discover a full essay, order it on our website:
