Yr 11 - Acid and Bases (VITAL)

Question 1

What is acid and base concentration?

Answer 1

Concentration refers to the number of moles per volume are contained within the solution. How many ions are available for reaction.

Question 2

What is acid and base strength?

Answer 2

How much of the acid or bases ions are disassociated in a solution.

Question 3

Reaction of metal carbonates with acids structure

Answer 3

metal carbonate + acid -> salt + water + carbon dioxide

Question 4

Reaction of metal oxide with acid structure

Answer 4

metal oxide + acid -> salt + water

Question 5

Reaction of base and acid structure (neutralisation)

Answer 5

base + acid -> salt + water

Question 6

Rules for naming ions

Answer 6

• Postive ions KEEP their name
• Negative monoatomic = ‘ion’-IDE (Chloride)
• Negative polyatomic ‘ion’-ATE (Sulphate)
  Exceptions: OH⁻ = Hydroxide & NH₄⁺

Question 7

What is an ionic bond

Answer 7

The force of electrostatic attraction that holds ions together with an ionic substance (+ -)

Question 8

What is particle theory?

Answer 8

All matter is made up of tiny particles (atoms, ions & molecules) and theyre in constant motion. Temperature , concentration, surface area and catalysis affect this speed.

Question 9

What is collision theory?

Answer 9

In order for a chemical reaction to occur, two + reacts must collide with a minimum amount of force to react, this is the activation energy.

Question 10

How does groups effect the element

Answer 10

Groups represent the number of electrons in the outermost shell.

Question 11

Name of groups 1,2,17&18

Answer 11

1  = alkali metals 
2 = alkali earth metals 
17 = halogens
18 = noble gases

Question 12

What effects the pH (concentration or strength)?

Answer 12

Concentration - represents the number of hydrogen or hydroxide ions.

Question 13

Types of reactions

Answer 13

base and acid, metal carbonates, metal oxide
