Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6. The acidity of rainwater comes from the natural presence of three substances (CO2, NO, and SO2) found in the troposphere (the lowest layer of the atmosphere). Carbon dioxide (CO2) is present in the greatest concentration and therefore contributes the most to the natural acidity of rainwater.
Hope this helps! :)

Why rainwater has a naturally acidic on limestone buildings?
As rainwater falls to earth, it absorbs pollution (natural and industrial) in the atmosphere which turns the rainwater slightly acidic. Limestone is affected by the acidity, and weathering and erosion is the result. The more pollution, the stronger the acidity, and the more damage is done to buildings and statues made from limestone.
Is rainwater natrually acidic?
Yes, rainwater is naturally slightly acidic due to the presence of carbon dioxide in the atmosphere. Carbon dioxide mixes with rainwater to form carbonic acid, which lowers the pH of the rainwater. However, human activities, such as emissions from burning fossil fuels, can increase the acidity of rainwater to harmful levels, leading to acid rain.
How do chemists express the degree of acidity or basicity of a substances?
ph scale
Which would de the most accurate way of measuring the acidity of rainwater from a rain gauge?
A standardized pH meter would be the preferred method to used.
Can melting glaciers increase ocean acidity?
No. Melting glaciers add clean fresh water to the oceans, so their melting decreases ocean acidity.
How does the acidity of acid rain compared to the acidity of natural rainwater?
Natural rainwater has a pH of around 5.6. I believe rain is considered to be "acid rain" when it has a pH of 5.0 or below.

One atmospheric compound is responsible after it has dissolved in water for both the general acidity of normal rainwater and the acidity of much soil What is this compound?
carbon dioxide
What does an increase of 1 pH number represent?
10x increase in acidity
Are substances that change color with respect to the acidity or basicity of a solution?
These substances are called pH indicators.

Does removing hydrogen increase or decrease acidity?
Removing the hydrogen ion H+ the acidity decrease.
What do the litmus strip drug tests show?
Acidity and alkalinity of substances.
How do chemists express the degree of acidity or basicity of a substances?
ph scale
What sentence correctly compares the acidity of acid rain to the acidity of natural rainwater?
Acid rain is slightly more acidic (has a lower pH) than normal rain.As an explanation the pHs of common materials (acids and basess) including Acid rain are:Lye 14.0Ammonia water 11.6Eggs 8.0Blood 7.3Distilled water 7.0Saliva 6.0Normal rain 5.7Acid rain 5.2Tomato Juice 4.2Apple Juice 3.0Coke products 2.5 to 4.2Vinegar 2.4
Can pH value be related to acidity?
Yes to lower acidity you can add alkalines which increase Ph values
Discuss how a coal-fired power plant increases the acidity of rainwater in that locality.?
because coal is a component that when added to water makes it polluted and increase the chance to have acid rain. By: Kieth S. From: De La Salle University Lives in: Forbes Park Manila
