What part of the world is most affected by acid rain?
What part of the world is most affected by acid rain?
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.
How is pH calculated?
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+]. Example: What is the pOH of a solution that has a hydroxide ion concentration of 4.82 x 10-5 M?
What is the pH of normal water?
6.5–8.5
What is pH stand for?
power of hydrogen
Why P in pH is small?
pH is an old abbreviation for a french description of the acidity of water. The French term is “puissance d’hydrogen”, which means “power or strength of Hydrogen”. The p is small because it refers to a word.
What is the pH value of human?
Life on earth depends on appropriate pH levels in and around living organisms and cells. Human life requires a tightly controlled pH level in the serum of about 7.4 (a slightly alkaline range of 7.35 to 7.45) to survive [1].
What is the pH of blood?
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.
What is the pH of blood What happens if the pH of blood changes?
Certain situations and medical conditions can mean that the body is unable to keep blood pH within the healthy range. The pH of the blood can change in both directions. Acidosis occurs when the blood is too acidic, with a pH below 7.35. Alkalosis occurs when the blood is not acidic enough, with a pH above 7.45.
What happens if the pH of blood changes?
If an increase in acid overwhelms the body’s acid-base control systems, the blood will become acidic. As blood pH drops (becomes more acidic), the parts of the brain that regulate breathing are stimulated to produce faster and deeper breathing (respiratory compensation).
