What are Acids? |
Acids are substances that produce hydrogen ions in aqueous solution |
hydrogen ions |
|
|
What are the properties of Acids? |
1. Sour taste 2. Dissolve in water to form solutions that conduct electricity 3. Turns blue litmus paper red 4. Acids react with reactive metals to form salt and hydrogen gas 5. Acids react with carbonates and hydrogen carbonates to form salt, water and carbon dioxide 6. Acids react with metal oxides and hydroxides to form salt and water |
6 properties |
|
|
What are alkalis? |
An alkali is a substance that produces hydroxide ions in aqueous solution |
Hydroxide ions |
|
|
What are the properties of alkalis? |
1. Bitter taste and soapy feel 2. Turns red litmus paper blue 3. Alkalis react with Acids to form salt and water (neutralisation) 4. Alkalis react with ammonium salts when heated to give ammonia gas |
4 properties |

What is the difference between a strong acid and a weak acid? |
A strong acid is an acid that ionised completely in water while a weak acid is an acid that only partially ionises in water. |
difference in ionisation in water |

|
How to identify basic oxides? |
1) All metal oxides are basic oxides 2) Basic oxides are insoluble (solids) 3) They behave like an alkali and neutralise with acids |
3 points |
|
|
How to identify acidic oxides? |
1) All non-metal oxides and dioxides are acidic oxides 2) Acidic oxides behave like an acid and they neutralise with alkalis |
2 points |
|
|
How to identify amphoteric oxides? |
1) ALZ oxides are all amphoteric oxide 2) They are insoluble (solids) 3) They can act like an acid and an alkali |
1) 2 points 2) Remember Amy Loves Zoro's Cat |
|
|
How to identify neutral oxides? |
1) All monoxides are neutral oxides 2) They do not react with acids or alkalis |
2 points |
|
|
What is a base? |
A base is any metal oxide or hydroxide that reacts with an acid to produce a salt and water only base + acid ----> salt + water |
