Answer 2

Answer:

1. In chemistry, pH (/piːˈeɪtʃ/, denoting 'potential of hydrogen' or 'power of hydrogen') is a scale used to specify the acidity or basicity of an aqueous solution. ... At 25 °C, solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic.
2. 6.8 to 7.6
3. 7.0 is considered neutral. Most freshwater aquarium tropical fish do best at a pH of 6.8 to 7.6, although certain fish may require higher or lower levels. The pH of an aquarium tends to drop over time due to the breakdown of organic material, and the best way to prevent this is through regular partial water changes.
4. The pH scale, ranges from 0 (strongly acidic) to 14 (strongly basic or alkaline). A pH of 7.0, in the middle of this scale, is neutral. Blood is normally slightly basic, with a normal pH range of about 7.35 to 7.45. Usually the body maintains the pH of blood close to 7.40.
5. Acidosis refers to an excess of acid in the blood that causes the pH to fall below 7.35, and alkalosis refers to an excess of base in the blood that causes the pH to rise above 7.45. ... Most of the acid is carbonic acid, which is created from carbon dioxide (CO2) and water.
6. A salt is the product of an acid-base reaction and is a much broader term then common table salt as shown in the first reaction. The following are some examples of neutralization reactions to form salts. ... The non-metal oxide gases react with water to produce acids (ammonia produces a base
7. The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes
8. The kidneys help maintain the acid–base balance by excreting hydrogen ions into the urine and reabsorbing bicarbonate from the urine
