1
Q

A
is the capacity to accept H+ ions
2
Q

A
HCO3-
3
Q

A
acid-mine water
4

A
CO2
7
Q
why can you have more human waiste for fertilizer in western soil compared to ontarios soil?
A
Ontario has more acidic soil, if you have acidic soil and metal iolns the metal ions retain the + charge so mobility is increased. if you have an alkaline environment (like western soil) then that metal will have a netural charge and less mobility.
