Question 19

What are three properties of bases? are they acceptors or donors?

Answer 19

Slippery. Bitter. Turns red litmus paper blue.

Acceptors

Question 20

Name three properties of acids. Are they donors or acceptors?

Answer 20

Sour. Reacts with metal. Turns blue litmus paper red.

Donors

Question 21

How do you know if an acid or base is strong or weak? (Not PH)

Answer 21

If that ionizes or dissossitates completely or partially in water

Question 22

What is pH a measure of

Answer 22

Hydronium (H3O+) Ion concentration in water

Question 23

What is the pH scale? Where is a strong base and a strong acid found on the scale?

Answer 23

Something that describes how acidic or basic something is. 14 is a high base and 1 is a high acid

Question 24

What is the unit used to measure a solutions OH or H concentration

Answer 24

Molarity

Question 25

What is the relationship between the OH & H concentration in a solution

Answer 25

The stronger the H concentration to lower the OH concentration and vice versa

Question 26

What a strong base have a low or high H concentration and what a strong acid have a lower high OH concentration

Answer 26

Strong base would have a low H concentration. A strong acid would have a low OH concentration

Question 27

What a strong acid have a weak or strong conjugate base

Answer 27

Weak

Question 28

What types of solutions make the best electrolytes

Answer 28

Strong acids and bases

Question 29

What are the products one acids and bases react? What type of reaction is this

Answer 29

Salt and water. Neutralization or double replacement

Question 30

What makes up a solution what are their roles

Answer 30

Solute - what gets dissolved Solvent - what does the dissolving

Question 31

What are three things that you could do to increase the rate of dissolving the salt in the solvent

Answer 31

One. Increase the temperature Two. Increase the energy Three. Decrease size of the solid

Question 32

How would increasing the temperature affect the solubility of N2 in a solvent? Why

Answer 32

It would decrease the solubility because N2 is already a gas.

Question 33

What property effects the solubility of a gas-liquid solution, but has no impact on a solid-liquid solution? And how does this impact of the solution?

Answer 33

Pressure As the pressure increases, the solubility increases also

Question 34

What happens when strong acids or strong bases dissolve in water?

Answer 34

It ionizes or dissossitates almost completely
