What is the range of pH in acid rain and how this is linked to the concentration of acid?

Answer 1

Strong acids have high pH, so If the concentration of acidic elements in the rain high, the pH of the rain solution is higher.

"In chemistry, pH is a measure of the acidity or basicity of an aqueous solution." Wikipedia

Note from a chemistry teacher on the answer above:

Several of my pupils have referenced this answer in their Coursework - it is WRONG!!!!

Strong acids eg HCl, are completely dissociated and therefore have a high concentration of H+ ions. Weak acids are only partly dissociated and so have a lower concentration of H+ions.

The pH scale is a measure of the concentration of H+ ions but because it is calculated using the negative log of the concentration, the LOWER the pH the HIGHER the concentration of H+ ions

So, answer above should read = strong acids have a LOW pH so if the concentration of acidic elements in the rain is high then the pH of the rain solution is LOWER

PS - kids - Wikianswers is not always the best place to use for your coursework - take care!!!!!

Answer 2

pH is the measure of acidity or alkalinity in a solution. Solutions are acids, neutral or bases.

• Pure water is "neutral" marking and means the pH level is 7.0.
• If pH falls below 7.0 the solution is an acid.
• If the pH rises above 7.0 and is a base.

The pH of acid rain is anything below 5.6.

Answer 3

Water is considered Acid Rain when it has a PH below 5.6. Water is regularly a 7 on the PH scale (this is nuetral). Below 7 is considered acidic and above 7 is considered a base.

Answer 4

Acid rain typically has a pH of 4.0 to 4.5.

Answer 5

anything under 5.6 but probablly less

Answer 6

Answer 7

The approx. pH of acid rains is 4.

Answer 8

5.2
