Quiz Answer Key and Fun Facts
1. What colour is methyl orange in alkali conditions?

Answer: Yellow

Methyl orange is one of the indicators commonly used in titrations. In an alkaline solution, methyl orange is yellow. In a solution becoming less acidic, methyl orange moves from red to orange and finally to yellow with the reverse occurring for a solution increasing in acidity. It should be noted that the entire color change occurs in acidic conditions.
2. Why is universal indicator a better indicator to use than litmus indicator?

Answer: Universal indicator gives the pH of the solution.

Universal indicator gives a range of colours that can be used to determine the pH of a solution. Litmus can only tell you whether something is acid alkali or neutral.
3. Which of the following substances when mixed together will produce table salt (sodium chloride)?

Answer: Hydrochloric acid and sodium hydroxide.

Hydrochloric acid + sodium hydroxide -----> sodium chloride + water
4. What colour would hydrochloric acid (pH 1) turn universal indicator?

Answer: Red

Strong acids turn universal indicator red. Weaker ones may turn it orange or yellow.
5. If I react magnesium with hydrochloric acid, what gas is produced?

Answer: Hydrogen

If you react a metal with an acid the gas given off is always hydrogen.
6. Which of the following is the most accurate way of showing neutralisation?

Answer: Acid + base ------> salt + water

An acid and base react together and produce a salt and water.
7. What are the products, if a reaction occurs between nitric acid and sodium hydroxide?

Answer: Sodium nitrate + water

Nitric acid + sodium hydroxide ----> sodium nitrate + water.
8. Aluminium will react with Hydrochloric acid. What are the products of this reaction?

Answer: Aluminium chloride + hydrogen

You can test for the hydrogen by igniting a small amount producing a squeaky pop.
9. What are the products when silver reacts with dilute sulphuric acid?

Answer: Silver doesn't react with dilute sulphuric acid.

Silver is an unreactive metal and would not react with acids, as it is less reactive than hydrogen.
10. If a base will dissolve in water, by what name is it better known?

Answer: Alkali

Most bases are not soluble, but if they are, they are referred to as alkalis.
