How to know the pH value of drinking water?


The sign for acidity and alkalinity is known as the pH value. A pH value of 7 indicates a substance are neutral. The lower value shows acidity, and a higher value is a sign of alkalinity. Do you Remember the times in school-days when we performed that experiment with litmus paper and it changed to red when you place it on a lemon and blue in soapy water? That was perhaps our very first lab experiences into the wondrous science of pH.

Essentials of pH Value

Essentially, the pH value is a good sign of whether drinking water is hard or soft. The pH of the pure water is 7. In most cases, water with a pH lesser than 7 viewed as acidic water, and with a pH bigger than 7 viewed as basic. The standard range for pH in earth's surface to water fallen in between 6.5 to 8.5, and the pH range for groundwater fallen in between 6 and 8.5. Alkalinity is the calculation of the potential of the water to resist a change in pH which are likely to make the water more acidic. The way of measuring alkalinity and pH are requires to decide the corrosives of the water.

Drinking water must have a pH value of 6.5-8.5

Impact on our life

Consuming too much of acidic or alkaline water is unhealthy for human, warns the Environmental Protection Agency (EPA). Drinking water should have a pH value ranging 6.5-8.5 to fall within EPA specifications, and they further see that even within the acceptable pH range, marginally high or low-pH water could unpleasant for various reasons.

High-pH water has a smooth feel, tastes a bit like baking soda, and may leaves tissue on fixtures, As per the EPA website. Low-pH water, however, may have a bitter or metallic flavor, and may lead to fixture corrosion.

Expert’s Insight

A research conducted by University points out with other problems associated with drinking water and pH: High-pH water is often hard. Further they said that hard water “does not create health risk, but can trigger aesthetic problems.” Amongst problems related with hard water, they list enhancement of level on fixtures, a bitter flavor, difficulty having soaps to lather, and decreased water-heater efficiency. They tells that drinkings water could be softened with ion-exchange water-softening equipment or devices.

According to an expert’s study, the relationship of pH with atmospheric gases and temperature is the main reason waters trial samples were examined. The study says that the pH values of the water is not a figure of the strength of the acidic or basic method, and alone cannot present a full picture of the characteristics or limitations with the water source.

Although the standard pH level of drinking waters should fall between 6 – 8.5, the human body preserves pH equilibrium and will not influence by water usage. Turtle Can illustrate this in more friendly way, our stomachs have a normal lower pH level of 2 which is a advantageous for acidity that helps us with digestion of food.
