Q

What is volumetric analysis

A

a process that uses the volume and concentration of one chemical reactant (standard solution) to determine the concentration of another unknown solution

17
Q

What are volumes measured with (2)

A

a volumetric or graduated pipette and a burette

18
Q

What are the 5 steps in making a standard solution

A
  1. weigh out a precise amount of the solid
  2. Add to a small volume of water and pre dissolve the liquid
  3. transfer to a volumetric flask
  4. Rinse the beaker with distilled water and add the rinsings to the flask
  5. make up to the scratch mark with more water and stopper and mix the contents
19
Q

Percentage uncertainty =

A

Uncertainty/measured value *100

20
Q

define concordant

A

within 0.1 CM3 of each other

21
Q

what is the uncertainty of a burette

A

±0.05 cm3

22
Q

What is the oxidation state for any uncombined element

A

Zero

23
Q

What is the oxidation state for group one elements

A

+1

24
Q

What is the oxidation state for group 2 elements

A

+2

25
Q

What is the oxidation state for Fluorine

A

-1

26
Q

What is the oxidation state for hydrogen and whats the expection

A

+1 except for in metal hydrides where it is -1

27
Q

What is the oxidation state for oxygen and 2 exceptions

A

-2 expect in peroxides where it is -1 and F20 where it is +2

28
Q

What is the oxidation state for ions

A

same as its charge

29
Q

What is the oxidation state for a compound

A

sum is zero

30
Q

How do you determine which atom is positive

A

the more electronegative atom will be negative

31
Q

Metal + acid ->

A

Salt + water

32
Q

what does increase in electron number mean

A

oxidation

33
