Rainwater is typically slightly acidic due to the presence of dissolved carbon dioxide, forming carbonic acid. When tested with a universal indicator, it usually shows a pH around 5 to 6, resulting in a pale yellow to green color, indicating a weak acidity. However, the exact color can vary depending on pollutants and other substances present in the rainwater. In areas with high pollution, the pH may be lower, resulting in a more pronounced yellow or orange color.
You add universal indicator and then compare the colour it turns to an example ph scale. The redder the Ui the more acidic it will be, if it is green it will be neutral and if it is blue/purple it will be alkali.
Rain is a liquid because it is water.
The water which evaporates fall as rain. The process is called precipitation.
Precipitation is water that falls from the sky in the form of rain or snow, but water vapour is a form of water that has evaporated into the air.
Rain water would normally boil at a slightly lower temperature than sea water, assuming the rain water has fewer dissolved particles in it compared to sea water.
It should turn the UI to a light yellow because it is a very mild acid. It has a pH level of around 6. Whereas a strong acid like Battery Acid (pH 1) would make it a red.

Unpoluted rain has a pH around 5.7 (very mild acid) but with typical levels of atmospheric polution in the US its pH is typically between 5.6 to 3.8 (mild acid) and exceptionally it can have a pH as low as 2 (fairly strong acidic) due to atmospheric polution such as Sulpher Dioxide which is disolved in the rain. Typically a universal indicator would show yellow for unpoluted rain, orange for mildly poluted rain and red for very poluted rain.
The color of water
Lichens are a good indicator species for acid rain. Lichens absorb water and nutrients from the air. They absorb the nutrients that they need from the water. Rainwater contains enough sulphur dioxide to make them stop growing.
Rain disturbes the silt at the bottom and causes it to rise in the water amking the murky-brown colour.
greyish
If there is a acid rain,the raindrops will be in yellow colour.
no. its normal coloured unless it is mixed with an indicator
The reason why rain water has no colour is because, the rain water travels up from the sea to form a cloud. The sea has not colour in it. That is why rain water has no colour. : ) No pure water has any color. The color(s) you see in water is/are due to the sunlight refracting into the colors of the rainbow, or due to impurities in the water. In the case of refraction, raindrops are so small that it's not easy to see an entire rainbow, so only a few of the more visible colors are seen. When the water has impurities (usually dust), sunlight illuminates the particles in different ways, causing the appearance of color.
We can make good use of rain water by storing rain water and by rain harvesting.
