Question 5

what does something being more dilute mean?

Answer 5

less concentrated

Question 6

how do we make a substance less concentrated?

Answer 6

dilute it

Question 7

how do we know if something is more dilute/less concentrated than another?

Answer 7

smaller number

Question 8

what’s the most accurate way to dilute a solution?

Answer 8

make one concentrated solution and dilute it (make it less concentrated)

Question 9

dilution equation

Answer 9

C1V1 = C2V2

Question 10

organ bath

Answer 10

tube with solution and tissue in it

Question 11

name for the starting drug solution

Answer 11

stock solution

Question 12

stock soluton

Answer 12

name for the starting drug solution

Question 13

10ml in mM

Answer 13

10

Question 14

10mM in ml

Answer 14

10

Question 15

what can V2 be in C1V1 = C2V2?

Answer 15

how much you add
(you don’t have to add it to the original volume - there’s only a small error)

Question 16

fold equation

Answer 16

x fold = starting conc./x

Question 17

what is %w/v for?

Answer 17

expressing solution concentration in terms of % (weight/volume)

Question 18

what does the % in w/v tell us?

Answer 18

how many g in 100ml

Question 19

100microL in ml

Answer 19

0.1

Question 20

0.1ml in microL

Answer 20

100

Question 21

when are logarithms particularly useful?

Answer 21

for interpreting graphs better

Question 22

anti-logs

Answer 22

10^x

Question 23

explain how to do log101microM

Answer 23

log of a micromolar
micromolar = 1x10^-6M
= -6 (same as the prefix value)

Question 24

Equation for working out the concentration of a new solution

Answer 24

Starting concentration/x

(For an x fold dilution

Question 25

Equation for working out the concentration of a new solution

Answer 25

Starting concentration/x

(For an x fold dilution)
