    • HCL?

      Hydrochloric acid, it produces fertelizers
    • H2SO4
      sulfuric acid, it produces detergents
    • NO3
      Nitric acid, used in production of ammonium nitrate
    • What is the PH scale?
      its shows acid or alkali substance
    • What is dilution?

      It is adding water to make it less concentrated
    • When a PH acid is diluted what happened?
      It increases to 7
    • what happened to PH alkali when diluted
      Decrease to 7
    • Match heads contain what?
      Small amount of sulfur
    • What is a base
      Base neutralise acid
    • What is the difference between base and alkali?
      A base is insoluble while an alkali insoluble
    • What happens to oxide when in water?
      It will dissolve to form an acidic solution
    • What happens to soluble metals when in water?
      It dissolves to make an alkali solution
    • Acid turns what colour were universal indicator
      Red
    • Alkali turns what colour of universal indicator
      Purple
    • Neutral turns, what colour of universal indicator?

      Green
    • What can acid rain harm?
      It can damage trees and it can make the pH too low for fish to survive
    • Name some bases
      Metal oxide metal hydroxide and metal carbonate
    • Titrations are what?

      They are used to measure how much alkali is needed to neutralise acid accurately
    • What can happen if there’s too much acid in our diet?
      We can lead to decay and kidney stones
    • Tell me about carbon dioxide gas
      Carbon dioxide gas can to form carbonic acid but is not one of the main gases to cause acid rain
    • What happens when an acid in a metal oxide or metal hydroxide react together?
      Water and salt are formed
    • What is the test for sodium carbonate?
      It turns lime water milky
    • What is the volume of acid called?
      Titre
    • Burning fossil fuels release what?
      Carbon dioxide, sulphur dioxide and nitrogen dioxide into the air
    • Carbon dioxide is one of the main what?
      Greenhouse gases and can affect global warm
    • The pH of water can only be affected by what?
      The addition of soluble substances
    • Titraition until you get what?
      Concorded results
    • Carbon dioxide is released into the atmosphere how?
      Respiration and burning fossil fuels
    • Carbon dioxide is removed from the atmosphere
      Photosynthesis
