Acids and Alkalis

Question 1

whats the general equation of an acid and base reaction

Answer 1

acid + base -> salt + water

Question 2

whats the general equation of an acid and alkali reaction

Answer 2

acid + alkali -> salt + water

Question 3

whats the general equation of an acid and metal reaction

Answer 3

acid + metal -> salt + hydrogen

Question 4

whats the general equation of an acid and metal carbonate reaction

Answer 4

acid + metal carbonate -> salt + water + carbon dioxide

Question 5

what is a base

Answer 5

solution that reacts with an acid to produce only salt and water

Question 6

what is an alkali

Answer 6

a soluble base

Question 7

what is a salt

Answer 7

an ionic substance with metal and non-metal ions

Question 8

Describe how the tritation of an acid and an alkali can be used to make a soluble salt

Answer 8

• using a pipette transfer a known volume of alkali into a conical flask
• Add a few drops of indicator
• Add acid from a burette slowly until You are near to the indicator changing colour (end point)
• Repeat the experiment with no indictator
• Evaporate the water from the solution to leave the salt

Question 9

What is an acid

Answer 9

acids produce hydrogen ions (H+) when it is dissolved in solution

Question 10

What is neutralisation

Answer 10

Neutralisation is when the hydrogen ions (H+) of an acid reacts with and are cancelled out by hydroxide ions (OH-) from aj alkali or by other substances

Question 11

ionic equation of neutralisation of an acid and alkali to make water

Answer 11

H+ + OH- -> H20
