With different amounts will there be a difference in what the results maybe? for example... will it neutralise the solution or will there be any insouble salt or the entire set up remains the same

# data[].attributes.body
Deionised water is used to get rid of impurities in the salt.

# data[].attributes.body
By adding different amounts of solution a and b, Will there be a difference in the amount of residue (aka insoluble salts) will be formed? if so... will there be any difference of how diluted or concentrated the salt maybe?

# data[].attributes.body
By using deionised water/distilled water, This is to get rid of the impurities that is stuck in the salts.

Plain water and tap water might have impurities in it thus , the experiment might not be accurate if you were to use plain water and tap water.

u add excess to ensure that the solution is neutral

When cold it does not react readily with such common metals as iron or copper. When hot it is an oxidizing agent, the sulfur in it being reduced; sulfur dioxide gas may be released. Hot concentrated sulfuric acid reacts with most metals and with several nonmetals, e.g., sulfur and carbon. 9

the amount of Solution A and Solution B should be the same amount to have a fair experiment

# data[].attributes.body
why need to use DI water? cleaner, purer

# data[].attributes.body
why must the saturated solution be cooled for the crystal to form

# data[].attributes.body
Why is deionised water needed in the preparation?

# data[].attributes.body
is solution a and b acid or base

# data[].attributes.body
can ionised water be used

# data[].attributes.body
Why do you need to put the deionised water when the salt is insoluble.

# data[].attributes.body
what is the thing in the filter paper?

# data[].attributes.body
how much solution B is needed?

# data[].attributes.body
Is it important to cool the soluble salt? Is there a difference if we immediately pour into the filter paper while it is still hot?

# data[].attributes.body
How much solution A in an insoluble preparation of salt is needed to have a complete reaction?

# data[].attributes.body
Why do you need to boil the pure solution

# data[].attributes.body
why must the sulfuric acid be hot in the preparation

# data[].attributes.body
why do you need to add excess

# data[].attributes.body
By adding the deonised water, why must we add this type of water. If we use tap water or any other type of plain water, will there be a difference?

Write down the steps for each of these method

Please look at the diagram carefully

# data[].attributes.body
Look at the picture on preparation of soluble salt. In this example, copper(II) sulfate is the soluble salt. Each group are to ask at least one question and questions should not be repeated among the group.

# data[].attributes.body
Look at the picture on preparation of insoluble salt. In this example, silver chloride is the insoluble salt. Each group are to ask at least one question and questions should not be repeated among the group.
