Acid Neutralizing Capacity

Question 0

ANC is the sum of the concentrations of

Answer 0

All proton acceptors minus the concentrations of all the OH- acceptors and proton doners.

Question 1

Anion neutralising capacity (ANC):

Answer 1

The ability of surface waters to resist acidification.

Question 2

Where magnesium and calcium are important components of the soil,

Answer 2

(Areas where weathering is high) there is usually enough ANC generation to neutralise acid deposition.

Question 3

In areas with low base cation concentrations and low weathering rates, the

Answer 3

Release of hydrogen carbonate into freshwaters is low and ANC generation is limited.

Question 4

Catchment hydrology can affect the reaction time between

Answer 4

The water and the soil particles and determine whether or not a catchment is ion-rich or ion-poor.
