Acids and Bases

    Cards (30)

    • Dilution is when you add water [H20] and the ph goes towards 7
    • Neutralisation is when you add an acid and a base together
    • A base is an alkali that dissolves
    • Ph measures the concentration of H+ ions
    • H+ ions are hydrogen ions
    • OH- ions are hydroxide ions
    • 1-6 are acidic and has the colour red/orange
    • 7 is neutral and is the colour green
    • 8-14 is alkaline and is the colour purple/blue
    • Acidic more H+ ions than OH- ions
    • Neutral equal amounts of OH- ions and H+ ions
    • Alkaline more OH- ions than H+ ions
    • sodium hydroxide = NaOH
    • potassium hydroxide = KOH
    • calcium hydroxide = Ca[OH]2
    • hydraulic acid = HCl
    • sulfuric acid = H2SO4
    • nitric acid = HNO3
    • metal + acid = salt + hydrogen
    • metal oxide + acid = salt + water
    • metal hydroxide + acid = salt + water
    • metal carbonate + acid = salt + water + carbon dioxide
    • acid + base = salt + water
    • ethanoic acid = ethanoate salt
    • sulfuric acid = sulfate salt
    • nitric acid = nitrate salt
    • hydraulic acid = chloride salt
    • non-metal oxides dissolve to give acidic solution
    • metal oxides dissolve to give an alkaline solution
    • insoluble metal oxides have no effect on the ph
