Process of becoming more acid pH 7 is neutral, above this is alkaline below pH 6 is acidic i e Acidification of the soil
is a process which occurs as a result of the deposition of atmospheric (air-borne) pollution containing acid-forming substances and ozone Acidification leads to damage to forests, heathlands, terrestrial and aquatic ecosystems, agriculture, public health, buildings and materials The acid forming substances are: Sulphur dioxide (SO2); Nitrogen oxides (NOx); Ammonia (NH3) The ozone-forming substances are: Volatile organic compounds (VOCs); Nitrogen oxides (Nox)
The most important substances contributing to acidification are SO2 and NOX These are released into the atmosphere when fossil fuels such as oil and coal are combusted Air pollution with these substances leads to acid deposition (acid rain) that can pollute forests, lakes and rivers, as well as buildings
Raising the acidity (lowering the pH) of a fluid by adding an acid ADVANCE \x 540
The most important substances contributing to acidification are and They are emitted to the atmosphere when fossil fuels such as oil and coal are combusted Air pollution by these substances leads to acid deposition (acid rain) that can damage forests, lakes and rivers as well as buildings
the decrease of acid neutralizing capacity in water or base saturation in soil caused by natural or anthropogenic processes
on unusually hot years or after late grape harvests resulting in over-ripe grapes, an acidification process may be necessary : some tartaric acid is then added to the must of the grapes
Refers to reducing something's pH, making it more acidic; also means the loss of ANC
Fall in the pH of soil and water due to precipitation containing dissolved ammonium compounds, sulphur and nitrogen oxides; an indirect cause of forest damage
- Changes in chemistry in an area that lead to a more acidic environment (e g acid rain)
The addition of acid (usually tartaric) during fermentation, frequently necessary in hot climates where grapes tend to overripen and become deficient in acidity, thereby losing freshness
The process by which rivers, lakes, rain, and other natural features become affected by excess acid For example, nitrogen dioxide may form toxic organic nitrates, which contribute to acid rain and the acidification of ground and surface water
The process of becoming acidic For example, as acid rain falls on a lake over the many years, the pH of the lake itself may drop (become more acidic); this process is called acidification
