Understanding the pH Value of Pure Water
Water is the most essential resource that is available on earth, which cannot be replaced by anything else. The human body is made up of around 60% water, which proves the importance of water for our survival. But, have you ever wondered what the pH of pure water is? Let's find out!
What is pH value?
pH is an abbreviation for "potential hydrogen." The pH value determines whether a substance is an acid or base. The pH scale ranges from 0-14 with 7 being neutral.
The pH Value of Pure Water
The pH of pure water is 7, which makes it neutral on the pH scale. This is because water molecules are made up of equal numbers of positively charged hydrogen ions (H+) and negatively charged hydroxide ions (OH-). So, the concentration of both H+ and OH- ions in pure water is equal, making it neutral.
Measuring pH Value
The pH value can be measured using pH paper or a pH meter. pH paper contains a pH indicator that changes color depending on the pH of the substance it comes in contact with. pH meter measures the electrical potential difference between two electrodes, which is converted into a pH reading.
The Importance of pH Value
pH is an important parameter to measure in various industries, including agriculture, food, and water treatment. In agriculture, pH can determine the nutrient availability in soil, while in food, pH can impact the flavor, texture, and safety of the food. In water treatment, pH can indicate the water's acidity or alkalinity and can determine the effectiveness of the treatment process.
Factors Affecting pH Value
There are several factors that can affect the pH value of water. These include dissolved gases such as carbon dioxide or oxygen, dissolved minerals such as calcium or magnesium, and organic matter such as leaves or decaying plants. Human activities such as industrial discharge and agricultural runoff can also significantly affect the water pH value.
Acidic and Alkaline Water
Water with a pH value lower than 7 is acidic, while water with a pH value higher than 7 is alkaline. Acidic water can be harmful to human health and can also corrode pipes, plumbing fixtures, and appliances. On the other hand, alkaline water can have a bitter taste and can cause mineral buildup in plumbing systems.
Purified Water pH Value
Purified water's pH value depends on its source, treatment process, and storage conditions. The pH level of purified water is usually neutral, but it can vary depending on the above-mentioned factors and human activities. Before drinking purified water, it is important to check its pH value to ensure its purity and safety.
Conclusion
The pH value of pure water is essential to understand, as it can affect the water quality and safety. The pH of pure water is 7, which makes it neutral on the pH scale. Measuring water pH can help identify the potential health risks and determine the appropriate treatment method. Maintaining the pH level of water is crucial for human health and the environment.
