pH is a measure of how acidic or alkaline a substance is. It is measured on a scale of 0 to 14, with 0 being the most acidic and 14 being the most alkaline. Pure water has a pH of 7, which is neutral. Many factors can affect the pH of water, including the presence of minerals, dissolved gases, and organic matter. Water with a pH below 7 is considered acidic, while water with a pH above 7 is considered alkaline or basic.
There are several reasons why you might want to reduce the pH of water. Acidic water can be corrosive to pipes and fixtures, and it can also leach metals from these materials into the water. Acidic water can also be harmful to aquatic life. Alkaline water, on the other hand, can be beneficial for health. It can help to neutralize stomach acid, and it can also help to prevent the formation of kidney stones.
