  • Acids, bases and salts
    • Acids
      • Types of Acids
        • Hydrochloric acid HCl
      • Hydrogen in acids
        • All acids form H+ ions when we add them to water. It is these H+ ions that make a solution acidic
        • All of the common types of Acid contain Hydrogen
    • Alkalis
      • Types of Alkali
        • Sodium Hydroxide NaOH
      • Solution more than 7. A base that is soluble in water dissociating into hydroxide ions.
  • OH-
    • All Alkalis contain  Oxygen and Hydrogen
    • Alkalis
      • Types of Alkali
        • Sodium Hydroxide NaOH
      • Solution more than 7. A base that is soluble in water dissociating into hydroxide ions.
  • Indicators
    • What are they?
      • Indicators are substances which change colour when we add them to acids and alkalis/base.
    • Different Indicators
      • Litmus Solution (Purple)
        • Acid: RED
        • Neutral: LIGHT PURPLE/BLUE
        • Alkali: BLUE/ DARK PURPLE
      • Universal Indicator
        • Acid: Red
        • Neutral: Green
        • Alkali Purple
      • Blue Litmus Paper
        • Alkali: Blue
        • Neutral: Blue
        • Acid: Red
      • Phenolphthalein
        • Acid: colourless
        • Neutral: Colourless
        • Alkali: Pink
      • Methyl Orange
        • Acid: Red
        • Neutral: Light Orange
        • Alkali: Dark Orange
      • Red Litmus Paper
        • Acid: Red
        • Neutral: Red
