Things to remember 2

Question 1

units of calculations

Answer 1

grams, ml and for ppm its same unit but multiply by 10^6 and is in relation to mass not quantity

Question 2

ion charge vs ion size

Answer 2

the effect of greater ion charge is greater than the effect of ion size. +2, -2 is stronger than relatively close nuclei

Question 3

C and M

Answer 3

c (little) is concentration while M is unit

Question 4

OH is a

Answer 4

OH is a non-polar bond

Question 5

ionizing/dissociating stuff

Answer 5

water’s polarity is close to the strength of the force of attraction to ionic compounds

bases are ionic so they dissociate in water
acids are molecular so they ionize.

Question 6

in a solubility thing…

Answer 6

• the min temperature is always not just the answer but “at least”
• when it says classify the solutions, you must say that it is saturated with sediment or if it is supersaturated

Question 7

why are smaller molecules more soluble than larger molecules?

Answer 7

its a SA thing

Question 8

amount of water in solution dilution

Answer 8

v final - v initial

Question 9

don’t mess up ml and l

Answer 9

just divide the number by 1000
