Soluble salts can be made by reacting acids with soluble or insoluble reactants. Titration must be used if the reactants are soluble. Insoluble salts are made by precipitation reactions.
Which salt would be formed by reacting cobalt carbonate and hydrochloric acid?
When a soluble salt is formed from an acid and an insoluble base, how do you know when an excess of base has been added?
When bubbles of gas appear
When the reactant all dissolves
When some of the reactant is left unreacted/undissolved
Why do you add excess of the insoluble reactant when making a soluble salt?
To make sure all the acid is used up
To separate the solid from the solution
To make sure a reaction occurs
How do you separate an excess insoluble reactant from a solution?
Which of these substances is most likely to be insoluble?
Magnesium chloride solution and sodium carbonate solution are mixed together. What substance is precipitated?
Which two chemicals could you react to make only potassium chloride and water?
Potassium and hydrochloric acid
Potassium hydroxide and hydrochloric acid
Potassium oxide and sulfuric acid
When producing a soluble salt in a reaction between an acid and an alkali, how can you prepare dry solid crystals from the solution?
When performing an acid-alkali titration, what piece of apparatus is used to place a fixed volume of the first solution into the conical flask?
Which two solutions react to make a precipitate?
Barium nitrate and sodium chloride
Potassium nitrate and sodium chloride
Lead nitrate and sodium chloride
