ACIDS AND BASES (anna) - Coggle Diagram

- - - - 2.acids turn blue litmus paper red
        
        acids have a pH value less than 7
        
        acids are corrosive
        
        acids conduct electircity
        
        acids react with 1 metal 2 carbonates 3 bases/alkalis
  - - - metals+acid-salt+hydrogen
      - acids react with metals to produce salt and hydrogen
      - e.g sulfuric acid(acid)+magnesium(metal)-magnesium sulfate(salt)+hydrogen
    - - 2.acid+carbonate-salt+water+carbon dioxide
        
        e.g nitric acid +sodium carbonate-sodium nitrate+water+carbon dioxide
      - carbonates contain metal/ammonium ion acids react with carbonate compounds to from salt water,carbon dioxide
    - - acid+metal-salt+hydrogen
      - e.g nitric acid +calcium(base)-calcium nitrate+water
      - acids react with bases/alkalis to form salt and water .reaction called neutralisation reaction
  - - - rust ,leather
        
        vinegar,preserve,adhesives
        
        preservative,flavouring

  - - - HCI
        
        HNO3
        
        H2SO4
    - - nitric acid

        magnesium hydroxide
        
        sodium hydroxide
        
        ammonia
    - - antacid
        
        antacid,toothpaste
        
        floor,oven-cleaners,soaps,detergent
        
        window cleaning solutions
  - - - they turn red litmus paper blue
        
        they are corrosive
        
        they conduct electricity
        
        react with acid produce salt+water. neutralisation reaction
        
        alkalis have ph value more than 7
- - - - litmus paper only indicate if a solution is acid or alkali,do not show how strong or weak
  - - - red 0-2 orange 3-4 yellow 5-6 pale green 7 green-blue 8-11 purple-violet 12-14
- - - - farmers test soil in pH to ensure soil pH is suitable for the plant species so can grow well
