Why pH is 10 for finding the hardness of water .something related to protonation?
A pH of 10 is often used when testing water hardness because it ensures that all carbonates and bicarbonates present in the water are fully ionized, allowing for accurate measurement of the total hardness. At this pH, the calcium and magnesium ions in the water form insoluble precipitates, which can be quantified to determine the hardness level. The high pH also helps to minimize interference from other ions in the water on the hardness measurement.
How would you use an indicator to find out if a solution is acidic-basic or neutral?
look at the pH level. If the pH is from 0 to 7, it is acidic. If it is exactly 7, that means it is water and it is neutral. 7 to 14 is basic.
Why cant the pH of aluminium oxide be measured?
Aluminum oxide is insoluble in water, so it does not produce an aqueous solution for pH measurement. Since pH is a measure of the concentration of hydrogen ions in a solution, it cannot be directly measured in the case of aluminum oxide.
Can pH indicator give accurate pH reading for solution?
An accurate measurement is made with a pH-meter; pH-papers make only approximative determination.
Ph scale in a sentence?
Here is a sentence: The pH scale is the measurement of how basic an object is or how acidic an object is.
Why DO you add KCl in dm water for measurement of pH?
Potassium chloride (KCl) is often added to distilled water to create a standard reference solution for pH measurements, known as a "buffer solution." This helps stabilize the pH of the solution and maintain its pH value when acids or bases are added. This ensures that the pH reading is accurate and reliable.
Why is pH important in science?
It is a precise measurement tool for determining how acidic (pH 0) to alkaline (pH 14) a solution of a chemical dissolved in water is.
Why is the measurement of pH an indirect measurement of cellular respiration in fish?
The measurement of pH is an indirect measurement of cellular respiration in fish because cellular respiration produces carbon dioxide as a byproduct. When carbon dioxide dissolves in water, it forms carbonic acid, which lowers the pH of the water. Therefore, an increase in cellular respiration in fish would lead to a decrease in pH in the surrounding water, making pH a useful indicator of the metabolic activity of the fish.
How can I test the pH of my tap water?
You can test the pH of your tap water using a pH test strip or a pH meter. Simply dip the test strip into the water and compare the color to the provided chart, or insert the pH meter probe into the water to get a digital reading. This will give you an accurate measurement of the pH level in your tap water.

What does the term "pH in water" refer to and how does it impact the quality of the water?
The term "pH in water" refers to the measurement of how acidic or basic the water is. pH levels can impact the quality of water by affecting its taste, safety for consumption, and ability to support aquatic life. Water with a pH of 7 is considered neutral, while lower pH levels indicate acidity and higher pH levels indicate alkalinity. Maintaining a balanced pH level is important for ensuring water quality and environmental health.
Does adding water change the pH of a base?
Yes, adding water to a base will dilute the solution, which can affect the pH. The pH of a basic solution may increase or decrease depending on the concentration of the base and the amount of water added.
What is water pH balance?
Water pH balance refers to the measurement of how acidic or alkaline water is. A pH of 7 is considered neutral, with values lower than 7 indicating acidity and values higher than 7 indicating alkalinity. Maintaining a balanced pH in water is important for aquatic life and human consumption.
What is the measurement called when measuring acid?
The measurement of acidity is called pH. It is a scale that measures the concentration of hydrogen ions in a solution, with lower pH values indicating higher acidity and higher pH values indicating lower acidity.
What substance on the pH scale is neutral and how do you know?
A substance with a pH of 7 is considered neutral on the pH scale. This means that it is neither acidic nor basic. A neutral pH indicates a balanced concentration of hydrogen ions and hydroxide ions in the substance.
What is the unit of measurement for pH?
The unit of measurement for pH is a logarithmic scale ranging from 0 to 14 that measures the acidity or alkalinity of a substance.
Can an indicator provide an exact pH?
An indicator can provide exact pH if you are using the neutralization titration. Paper strip pH indicator are not an exact measurement but a high, medium, and low indication of acids and bases.
