As acid rain falls or drains into the lake the pH of the lake falls.

When it is washed into lakes, aluminium irritates the outer surfaces of many fish. When acid rain falls on the ground it dissolves and liberates heavy metals and aluminium (Al). Although it is invaluable in the atmosphere, low level ozone causes respiratory problems and also hastens the formation of acid rain.

Hydrocarbons emitted by for example, car exhausts will react in sunlight with nitrogen oxides to produce ozone. Acidication increases with the number of active hydrogen (H+) ions dissolved in acid. My holiday was My mother cooked me very yummy. Soal di bawah ini adalah pilihan ganda, selamat memilih salah satunya ya 1. More ammonium (NH4) can be formed when some of the acids are partially neutralized by airborne ammonia (NH3). Berikut adalah 10 contoh soal UAS Bahasa Inggris 6 SD, Final Test untuk Semester 1. Catalysts such as hydrogen peroxide, ozone and ammonium help promote the formation of acids in clouds. The acids usually dissolve in cloud droplets and may travel great distances before being precipitated as acid rain. Sulphuric acid (H2 SO4) and the nitrogen oxides will become nitric acid (HNO3). If they are in the atmosphere for any time, the gases will oxidize (gain an oxygen atom) and go into solution as acids. The gases may be dry deposited–absorbed directly by the land, by lakes or by the surface vegetation. Most sulphur leaves factory chimneys as the gaseous sulphur dioxide (SO2) and most nitrogen is also emitted as one of the nitrogen oxides (NO or NO2), both of which are gases. When they burn, they make sulphur dioxide (SO2). Acid rain comes from sulphur in coal and oil.
