Neutralisation Reaction Flashcards
What is a Neutralisation Reaction?
A neutralisation reaction is the result of an acid and base reacting together to achieve a pH of 7.
How can solid salt be obtained using a neutralisation reaction?
It can be obtained by using the evaporation method.
List 3 uses of Neutralisation
- Treating indigestion - Neutralised by magnesium hydroxide (milk of magnesia)
- Wasp stings - Since they are alikaline, they can be neutralised by using ethanoic acid/acetic acid (vinegar).
- Acid soils - Can be treated with calcium hydroxide (lime)
What is salt?
Salt is a compound made up of a metal and non-metal part.
What type of substance is the metal part of salt?
Alkali
What type of substance is the non-metal part of salt?
Acid
How would we correct the pH of water that wasn’t 7
Neutralisation.
Name all the equipment used for evaporation
Evaporation Basin, Tripod, Gauze, Bunsen Burner
What is the first aid treatment for an acid or base burn?
Neutralising the area by washing under a tap.
How does a Neutralisation Reaction happen?
When an acid and alkali react with eachother (in correct proportions), they are neutralised and produce a salt and water.
What is the word equation for a Neutralisation reaction?
Acid + Alkail(or base) → Salt + Water
(DO NOT USE AN EQUAL SIGN, ONLY USE AN ARROW.)
What is the answer to this word equation?
Sodium Hydroxide + Hydrochloric Acid → __________
Sodium Chloride + Water
(ALWAYS REMEMBER TO ADD WATER ON TO THE ANSWER AS SHOWN ABOVE.)
