What is the pH in chemistry?
pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. The pH of water is a very important measurement concerning water quality.
What is the relationship between pH and the concentration of ions in solution?
The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale (Figure 1). Therefore, the more hydrogen ions present, the lower the pH; conversely, the fewer hydrogen ions, the higher the pH.
What is pH formula?
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].
Which country is most affected by acid rain?
United States and Canada are the countries which are mostly affected by acid rain because of high number of factories, power plants and large number of automotive plants. Europe, Poland, Germany, Czech Republic, Sweden, Norway and Finland are affected because of British and European factories.
Where is acid rain located?
Acid rain is responsible for severe environmental destruction across the world and occurs most commonly in the North Eastern United States, Eastern Europe and increasingly in parts of China and India.
When did acid rain become a problem?
Why has acid rain become an international problem?
Acid rain includes all types of precipitation with acidic content with a pH value of less than 7. Acid rain is referred to as an international problem because the emission of pollutants does not equally deposit in that country. Many countries emit a very small amount of pollutants and deposition can be greater.
What is acid rain write its effect?
When the accumulated acids are washed off a surface by the next rain, this acidic water flows over and through the ground, and can harm plants and wildlife, such as insects and fish. The amount of acidity in the atmosphere that deposits to earth through dry deposition depends on the amount of rainfall an area receives.
