Soluble salts can be made by reacting acids with soluble or insoluble reactants. Titration must be used if the reactants are soluble.
Which of these substances is a base?
Why is sodium chloride not made by reacting sodium with hydrochloric acid?
The reaction would be too slow
The reaction would not produce sodium chloride
The reaction is too vigorous
Which type of salt is made from sulfuric acid?
What is the name of the salt made by reacting zinc oxide with nitric acid?
Why is it important to add copper oxide to sulfuric acid until it is in excess when making copper sulfate?
If too little is added, the product would be copper sulfite
Adding excess copper oxide makes the reaction faster
Adding excess copper oxide makes sure the acid has all reacted
Which process is used to obtain solid zinc chloride from a solution of zinc chloride?
What is used in a titration to show when the acid and alkali have exactly reacted together?
What name is given to titre values in a titration that are within 0.20 cm3 of each other?
In a titration, a student recorded titre values of 21.20 cm3, 21.10 cm3 and 21.60 cm3. What value should the student give as the mean titre?
Why is titration used when making a salt from a soluble base?
The reaction is slower and more controlled
The acid does not need to be heated
The reaction needs an indicator to show when it is finished
