  • Acids and Alkalies
    • Acids turn litmus paper blue and alkalies turn litmus paper red
    • Acids and alkalies  can help neutralise each other
    • Acids taste sour and alkalies taste bitter
    • Alkalis have more hydrogen atoms than acids because alkalies range from 8-14 on the pH scale and acids range from 0-6 and that
    • Acids contain hydrogen ions and alkalies contain hydroxide ions
    • Alkalies feel soapy to the touch
    • Strong acids turn universal indicator red and strong alkalies turn universal indicator dark purple
    • Acids usually react with metals to form salts
    • Some Common lab acids are sulphuric acid, hydrochloric acid, nitric acid
    • Some common lab alkalies are sodium hydroxide, potassium hydroxide, ammonia
