Answer 29

(H+) is greater

Question 30

The solution is neutral if

Answer 30

They are the same

Question 31

pH<7 it’s

Answer 31

Acidic

Question 32

pH>7

Answer 32

Is basic

Question 33

To find it it’s acidic basic or just rap you look at the..

Answer 33

pH

Question 34

Weak base is

Answer 34

A anion that is a conjugate base of a weak acid

Question 35

A strong acid or neutral idk how to put this

Answer 35

An anion that is the conjugate base of a strong acid is neutral

Question 36

Solution is an acid when

Answer 36

H+ is bigger

Question 37

Solution is basic when

Answer 37

OH is bigger

Question 38

Buffer system

Answer 38

Aqueous solution that contains a weak acid or base and it’s conjugate

Question 39

What does a buffer system do?

Answer 39

It resist a large changes in pH by neutralizing strong acid or base pair. The weka acid neutralizes an incoming strong base and the weka base neutralize an incoming strong acid

Question 40

Buffer is written

Answer 40

Weak Acid and conjugate base( don’t worry about the cation)

Question 41

Effective buffer (3)

Answer 41

-Most resistant to pH changes - high concentration of acid and conjugate base) -close to an equal amount of acid and conjugate base

Question 42

Titration

Answer 42

Determining a concentration of an unknown

Question 43

PH meter

Answer 43

Device that measures voltage and converts H+ into solution

Question 44

To find pH

Answer 44

Use the sigmoidal curve to find at the equivalence point

Question 45

Equivalence point

Equivalence point of a strong acid/strong base will be at

Answer 46

7

Question 47

Indicator

Answer 47

A substance usually a weak acid that undergoes a color change at a specific pH range

Question 48

Endpoint

Answer 48

Just after the equivalence point and a great estimator for equivalence point

Question 49
