ACID DEPOSITION |
precipitation (in the form of rain, snow, hail, dew, or fog) that carries sulfur and nitrogen compounds from the upper atmosphere to ground level |
|
|
IDENTIFY ONE OXIDE WHICH CAUSES ACID DEPOSITION |
Sulfur dioxide (SO2) (which reacts to form HzSO4 and H2SO3) Sulfur-containing gases are discharged from erupting volcanoes and rotting vegetation. |

|
HOW TO REVERSE DECREASING PH OF LAKE WATER? |
Could be reversed through adding calcium carbonate which would neutralize lake water |
|
|
SHELL FISH + CALCIUM CARBONATE SHELL. Long term effect of acid deposition on these organisms. |
H2SO4 + CaCO2 —> H2O + CO2 + CaSO4 Acid deposition would cause the calcium carbonate shell to break down and erode over time. |
|
|
Examples of amphiprotic species |
HCO3- / HSO4- / H2O / H2PO4- / HPO4^2- |
|
|
Acid + base (metal oxides, hydroxides) ——> |
salt + water |
|
|
Metal + acid —-> |
Salt + Hydrogen |
|
|
Metal carbonate + acid —-> |
Salt + Water + Co2 |
|
|
Describe a strong acid |
Completely dissociates in water, more H+ ions, high conductivity |
|
|
Describe a weak acid |
Partially dissociates in water, few H+ ions, less conductive |
