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 exercises blue litmus test radical red. Strong bitters with a pH of 1 or 2, crack more hydrogen ions and be in truth corrosive slice weak acids with a pH of 5 or 6 contain less hydrogen ions therefore, they be not that corrosive. When an acid is added with a metal, salt and hydrogen be 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 hydr ochloric acid and putting the disposed 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 + weewee + Carbon DioxideNa2CO3 + 2 HCl ? 2 NaCl + H2O + carbon dioxideThe imperturbable carbon dioxide will therefore turn limewater cloudy. Limewater is a uncouth 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 dioxi! de 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 weaken a full essay, order it on our website: OrderCustomPaper.com
