pH measurement is an important parameter in nearly every water quality application. In environmental sampling and monitoring, high or low pH values can be indicative of pollution. To determine the pH of water, a pH meter can be used to measure this impor
An acid is a substance with a PH of less than 7. The pH scale measures how acidic or alkaline a substance is. A neutral substance such as pure water has a pH of 7! Acids form H+ions in water. The higher the concentration of H+ions, the more acidic the solution is. Examples of ...
Understand the pH value scale, learn several methods for determining pH, and understand the principles of methods for determining pH. Related to this QuestionIf you have an acidic solution with a pH of 4.6, what is the concentration of hydrogen ion...
What is an Acidifier? A soil acidifier is a product used to lower the pH of soil and make it more acidic. Lowering the pH of soil is needed in regions where the soil pH is too high, usually from a high lime, calcium, or magnesium content in the soil or water. Soil acidifiers are...
An increase in the amount of hydrogen ions (H+) causes the water to become more acidic. An increase in the amount of hydroxide ions (OH-) causes the water to become more alkaline. When measured, this is referred to as the pH of the water. ...

While adding baking soda can help to stabilize the pH level, it should be done in moderation as adding too much baking soda can lead to an excessive rise in pH, which can be difficult to correct. Another alkaline substance that can contribute to a high pH level is calcium carbonate. This...
What is K_a of an acid if a 0.100M solution has a pH of 5.30? Which is more acidic, a solution having a pH of 4 or one having a pH of 5? (a) What is the pH of 6.2 \times 1^{-3} M HCI? (b) What is the pH of 8 \times 10^{-8} M HCI?
that Brnsted-Lowry bases have in common with each other is that they have an unshared pair of electrons. When a hydronium ion comes wandering by the molecule, sometimes the lone pairs will reach out and grab it. An example of this is when ammonia accepts a proton in an acidic solution:...
What is Citric Acid? Citric acid, also known as sour salt, is a natural preservative and flavor enhancer, It adds an acidic sour taste to recipes but in many cases in very small quantity, it makes a very good substitution for lemon juice. This product dates back to the eighteenth century...
