|
Method and reagents for sodium chloride? |
titration (acid and alkali), HCl and sodium hydroxide
|
|
|
Method and reagents for calcium chloride?
|
acid reaction with excess insoluble substance. Hydrochloric acid with calcium carbonate, or calcium hydroxide. Cannot use calcium as it is highly reactive with acids and could explode.
|
|
|
Method and reagents for barium sulfate?
|
precipitation. Use two soluble salts, barium nitrate and sodium sulfate.
|
|
|
Method and reagents for barium chloride?
|
acid reaction with excess insoluble substance. Hydrochloric acid and barium carbonate. You can also use barium oxide or barium hydroxide.
|
|
|
Method and reagents for lithium sulfate?
|
titration (acid and alkali), sulfuric acid and lithium hydroxide
|
|
|
Method and reagents for calcium sulfate?
|
precipitation. Use two soluble salts, calcium nitrate and sodium sulfate.
|
|
|
Method and reagents for lead (II) chloride?
|
precipitation. Use two soluble salts, lead (II) nitrate and sodium chloride.
|
|
|
Method and reagents for copper(II) nitrate?
|
acid reaction with excess insoluble substance. Nitric acid and copper (II) oxide or copper (II) carbonate. Cannot use copper as it does not react with dilute acids. (see reactivity series)
|
|
|
Method and reagents for potassium sulfate?
|
titration (acid and alkali). sulfuric acid and potassium hydroxide
|
|
|
Method and reagents for magnesium chloride?
|
acid reaction with excess insoluble substance. Hydrochloric acid and magnesium carbonate.
|
|
|
Method and reagents for silver chloride?
|
precipitation. Use two soluble salts, silver nitrate and sodium chloride.
|
|
|
Method and reagents for lead(II) sulfate?
|
precipitation. Use two soluble salts, lead (II) nitrate and sodium sulfate.
|
|
|
Method and reagents for copper(II) sulfate?
|
acid reaction with excess insoluble substance. Copper (II) oxide or copper (II) carbonate and sulfuric acid. Cannot use copper metal as it does not react with dilute acids. (see reactivity series) |
|
|
Method and reagents for copper(II) nitrate? |
acid reaction with excess insoluble substance. Copper (II) oxide and nitric acid. Cannot use copper metal as it does not react with dilute acids. (see reactivity series) |
|
|
Describe briefly how precipitation is carried out. |
Precipitation needs two soluble salts. Dissolve the two salts in a beaker. Filter out the insoluble salt as residue. Wash the residue with distilled water and dry it. (in summary... dissolve, filter, dry residue) |
|
|
Describe briefly how acid reaction with an insoluble substance is carried out. |
Add the required acid to an excess of the insoluble substance and mix thoroughly until no further reaction is observed. |
