Worksheet Overview

QUESTION 1 of 10

Metal oxides contain atoms of a metal combined with atoms of oxygen. The black powder copper oxide is an example of a metal oxide.

Metal oxides react with acids to produce a salt and water. This can be shown in an equation:

Acid + Metal oxideSalt + Water

 

The salt produced from these reactions is dependent on the acid that is used. Metal oxides form chloride salts when reacting with hydrochloric acid, nitrate salts when reacting with nitric acid and sulfate salts when reacting with sulfuric acid.

An example of each type of salt formed is shown in the equations below:

 

Chloride Salts

Hydrochloric acid + sodium oxideSodium chloride + Water

HCl+ Na2ONaCl + H2O

Sulfate Salts

Sulfuric acid + calcium oxidecalcium sulfate + Water

H2SO4+ CaOCaSO4 + H2O

Nitrate Salts

Nitric acid + copper oxidecopper nitrate + Water

 

HNO3+ CuOCu(NO3)2 + H2O

 

It is important to learn the formulas of the acids, as they are the three most commonly used acids in the science lab.

salt and hydrogen

salt and oxygen

metal oxide and water

  • ANSWERS
  • Question 1

What are the two products of the reaction between a metal oxide and an acid?

CORRECT ANSWER
salt and water
EDDIE SAYS
The reaction between an acid and a metal oxide produces a salt and water.
  • ANSWERS
  • Question 2

Which of the following is not the correct name of an acid?

CORRECT ANSWER
celtic acid
EDDIE SAYS
Nitric, sulfuric and hydrochloric acids are all commonly used in the school lab and as such it is important to learn both their names and their formulas.
  • ANSWERS
  • Question 3

Match each of the formulas below to the correct acid name using the letters A, B and C:

A = HCl

B = HNO3

C = H2SO4

 

CORRECT ANSWER

Column A

Column B

A
hydrochloric acid
B
nitric acid
C
sulfuric acid
  • ANSWERS
  • Question 4

Identify the acid that can be used to produce the salts shown. 

CORRECT ANSWER
 Hydrochloric acid Sulfuric acid Nitric acid
Sodium chloride
magnesium nitrate
potassium chloride
aluminium sulfate
ammonium nitrate
zinc chloride
EDDIE SAYS
The name of the salt produced in these reactions gives clues to the acid used.
  • ANSWERS
  • Question 5

Which of the following salts is not produced from nitric acid?

CORRECT ANSWER
calcium sulfate
EDDIE SAYS
This one should be fairly straight forward. The clue is in the name.
  • ANSWERS
  • Question 6

Complete the equation by typing the name of the missing chemical into the text box below.

 

Calcium oxide + Hydrochloric acid __________  __________ + Water

CORRECT ANSWER
calcium chloride
EDDIE SAYS
The metal from the oxide combines with the the acid to form a salt.
  • ANSWERS
  • Question 7

Complete the following equation by typing the name of the missing compound into the text box below. 

______________  __________ + sodium oxide sodium chloride + Water

CORRECT ANSWER
hydrochloric acid
EDDIE SAYS
Word equations are used very often in science - remember the reactants are on the left and the products on the right!
  • ANSWERS
  • Question 8

Complete the equation by typing the name of the metal oxide used in the reaction into the text box below.

__________  ________ + Nitric acid  Sodium nitrate + Water

CORRECT ANSWER
sodium oxide
EDDIE SAYS
The 'sodium' in the salt name suggests that sodium oxide must have been used in this reaction.
