The pH value of water is the measurement of alkalinity and acidity. This value is also a good indicator of the level of hardness and softness in water. In fact, it is a necessary measurement for determining corrosiveness in water. Continue reading to learn more about pH values of water, and how to test your drinking water at home.
Water pH Measurements
Water pH levels are measured on a scale of zero to fourteen. A pH value of 7 is known “basic”, which is a neutral measurement. This is considered “pure” water. Rain generally has a pH value close to seven. As the numeric value increases above 7, the water becomes more alkaline. As the numeric value decreases below 7, the water becomes more acidic. Here are some fun pH level examples of everyday items you encounter:
Orange Juice 3.5 pH
Apple Juice 3 pH
Milk 6.2 pH
Coffee 5.5 pH
Bleach 12 pH
Baking Soda 8.5 pH
Soap Water 10 pH
As you can see, orange juice, apple juice and coffee are on the acid side, while milk, baking soda, soapy water, and even bleach are on the alkaline side. Surface waters generally retain pH values between 6.5 and 8.5, and groundwater retains a similar average. As for drinking water, acidic levels can indicate a presence of hard mineral ions like iron, manganese, copper, lead, and zinc. Fortunately, there are various soft water and filtration systems available to combat toxic and heavy metals in drinking water. These systems include while house water filters, reverse osmosis systems, water purification systems, and water softeners.
To test your own water or liquid, simply purchase some litmus test strips online, at a superstore, or at your local home improvement store. Simply dip it inside the substance, let it dry, and compare the colors to the chart provided. Usually, reds and oranges indicate acidity, while blues, greens, and purples indicate the opposite.
