Flashcards in Unit 2 - Acids, Bases and Salts Deck (15):
1

 What range of pH do acids have?

1-7

2

What is the equation for when metals react with acids?

Acid + Metal → Salt + Hydrogen

3

When reacting acids with metals: the more reactive the metal..

The faster the reaction will go (very reactive metals eg sodium react explosively)

4

When reacting acids with metals: how is the speed of the reaction indicated?

By the rate at which the bubbles of hydrogen are given off

5

When reacting acids with metals: how is it confirmed that the gas being given off is hydrogen?

By the burning splint test giving a 'sqeaky pop'

6

What does the name of the salt produced depend on?

Which metal is used and which acid is used

7

What salts will hydrochloric always produce?

Chloride salts eg magnesium chloride

8

What salts will sulfuric acids always produce?

Sulfate salts eg aluminium sulfare

9

What does nictric acids react with alkali's to produce?

Nitrates

10

Some metal oxides and metal hydroxides dissolve in water, these soluble compound are?

Alkali's

11

What do all metal oxide and metal hydroxides react with acids to form?

A salt and water

12

Give 4 properties of Acids

  • Corrosive 
  • pH of less than 7
  • React with and neutralise bases
  • Produce hydrogen ions in water

13

Give 2 properties of bases

  • They react with and neutralise acids
  • They are generally solids, but may be used in solution

14

Are metal oxides and metal hydroxides acids, bases or salts?

bases
