Chemistry: Acids and Alkalis

• Acid

  Produces a hydrogen ion when in solution
• base

  Substance that reacts with an acid and produces a salt and water only
• alkali

  Soluble base
• strong acid

  Will produce a lot of hydrogen ions when in solution
• weak acids

  Only produce a very small amount of hydrogen ions when in solution
• strong alkali

  Produce a lot
• weak alkali

  Only produce a very small amount of hydroxide ions when in solution
• Indicator

  A die which changes colour depending on whether the solution it is added to an acid or alkali
• strong acids

  • hydrochloric acid
  • sulfric acid
• strong alkalis

  • sodium hydroxide
  • pottasium hydroxide
• weak acids

  • ethanoic acid
  • carbonic acid
• weak alkalis

  • ammonia
  • ethylamine
• Acid properties

  • soluble in water, forming acidic solutions
  • tend to taste sour
  • can be corrosive
  • produce hydrogen ions in solution
• Alkali properties

  • are soluble in water, forming alkaline solutions
  • remove the sour taste of acids
  • are soapy
  • can be corrosive
  • produce hydroxide ions in solution
• Neutralization helps us in daily life, the environment, and industry by counteracting harmful acids or bases.
• For method writing in the field of "is it an acid or an alkaline," rememeber to include to mention equipment used/needed in the experiment, that goes for every method.
• three things you might see in a chemical reaction

  1. bubbling
  2. colour change
  3. potentiel heat
• three metals that don't react with acids

  1. magnesium
  2. zinc
  3. iron
• indicators and their colours in acids and alkalis
