Acidic vs. Alkaline
When soil and water meet, their acidity levels interact and combine to influence both. Ultimately, the water drains away and the soil assumes a slightly different acidic content. The acidity of the soil is very important, since how acidic or alkaline a soil is governs what kind of plants can grow there and how easily roots can extract the necessary nutrients to survive. In both water and soil, acidity is measured according to the pH scale, a negative logarithmic scale where values increase times ten per whole digit increase or decrease. The middle of the scale is 7, where the pH level is neutral (like pure water). Higher pH levels indicate alkalinity and lower levels indicate acidity.
The pH level is naturally changed by encounters with other materials. In the encounters between water and soil, soil is generally the most changed of the two, while water tends to stay the same or be purified by its encounter, moving closer to a neutral pH level.
When water vapor forms into clouds and moves into its rainfall phase, it combines with many different particles that are floating in the atmosphere. Some of these particles have very little effect on the rain, while others can adjust its chemical properties slightly. Certain acidic particles can combine with the water and give it a lower overall pH level. When this water falls as rain, it encounters other substances, notably the soil it eventually trickles down into.
Soil naturally holds minerals that are alkaline in nature, traces of limestone and other types of rock that possess similar qualities. When the acid particles of the falling water encounter these minerals, a chemical reaction occurs that neutralizes the acidity of the water but also neutralizes the minerals. This increases the acidity of the soil, but levels the water largely neutral in acidic content as it makes its way down to the water table.
In areas that experience heavy rainfall, the water tends to wash away alkaline element or neutralize them with chemical reactions. In this case, if a large amount of acidic water falls into the soil, it may not lose all of its acidic qualities and contribute to a lower overall pH level of the nearby water supply. However, most acidic elements in water are neutralized by encounters with bedrock even in the soil cannot handle them.
Soil pH is largely a factor of the ratio of the soil's organic matter content to its mineral component. Soils high in organic matter have a lower pH. The kind of minerals can also have an effect on pH.
It always depends on the kind of soil you have.If for example you work on acidic soil your water Ph will tend to get acidic.
Sometimes it can damage plant growth
In order to find the pH you will need to test the soil. Different factors will effect the pH and different plants grow better at a different pH. I heard its ph level is "6" the ideal fertilizer for gardening. Its neutral. The ph levels go from 0-11 :)
They do not have any effect

7.What effect does water pH have on the rusting of nails?
Acid rain has a low pH indicating that it is acidic. The pH in the soil can have a detrimental effect on some trees.

raising the pH of the water
Sodium bicarbonate increases the pH of water.
Adding hydrogen chloride to water the pH decrease.

Decreasing the temperature of water the value of pH increase.
These molecules haven't an effect on pH.
Heating pure water the pH decrease.
