Where to get good notes of acid bases and salts? |
Answer» \xa0Acids\t\tAcids is defined as the one which produces hydrogen ions in water.\xa0For Example, Sulphuric Acid, Hydrochloric Acid etc.\t\t\tThey give sour taste.\t\t\tAcids turn blue litmus to red. This is used as confirmation test for the presence of acid.\t\t\tWhen acids react with metals, gases are evolved.\tReactions with Acids1. Reaction of Acid with MetalAcid + Metal → Salt + Hydrogen gasMg + H2\xa0SO4\xa0→ H2\xa0+ Mg SO42. Reaction of Acid with CarbonatesNa2\xa0CO3\xa0(s) + 2 HCl (aq) → 2NaCl (aq) + H2O(l) + CO2(g)3. Reaction of Acid with BicarbonatesNaHCO3\xa0(s) + HCl (aq) → NaCl(aq) + H2O (l) + CO2\xa0(g)Similarity between Acids and Bases\t\tBoth acids and base react with water. They produce ions in water\t\t\tBoth acids and bases acts as electrolytes, so are good conductors of electricity.\t\t\tBoth of them changes the colour of the litmus paper.\t |
