Give an example of aa neutral liquid 7 Water or Vodka 1 of 12 What pH numbers indicate that a substance is acidic? 0-6 2 of 12 What pH numbers indicate that a substance is alkaline? 8-14 3 of 12 Can you give 2 (of each) examples of lab acids and alkalis? Acid= hydrochloric acid and sulphuric acid. Alkali= ammonia and sodium hydroxide. 4 of 12 What safety precautions are necessary when using lab acids and alkalis? 1) Wear safety specs at all times 2) Wash spills with lots of water 3) Tell a teacher is anything spills. 5 of 12 What do acids and alkalis do to each other when they react? They cancel each other out and they neutralise. 6 of 12 Can you give 2 examples of neutralisation in real life? 1)Too much acid in the stomach causes digestion. The medicines used to cure indigestion contain alkalis. This neutralises the excess stomach acid. 7 of 12 Can you give 2 examples of neutralisation in real life? 2) An acid, like vinegar, is used to neutralise a wasp sting, which is alkaline. 8 of 12 Write general word equations for all neutralisation reactions. Give one specific example of each type. 1) Nitric Acid + Lithium Hydroxide - Lithium Nitrate + Water 9 of 12 Write general word equations for all neutralisation reactions. Give one specific example of each type. 2) Sulfuric Acid + Tin Hydroxide - Tin Sulfate + Water 10 of 12 Write general word equations for all neutralisation reactions. Give one specific example of each type. 3) Phosphoric Acid + Zinc Hydroxide - Zinc Phosphate + Water 11 of 12 Write general word equations for all neutralisation reactions. Give one specific example of each type. 4) Hydrochloric Acid + Lead Hydroxide - Lead Chlorice + Water 12 of 12
