What is the use of a pH Meter in the laboratory?
A pH meter determines acidity or alkalinity of a substance.
How do you find the pH of a substance?
You use a litmus indicator.
If the ph of a substance is 11 then that substance is?
If a substance has a PH of 11 then the substance is basic.
What is the pH of a substance?
The pH is the negative log of the concentration of hydronium ions. (pH=-log [H3O+]) If the pH is high, the substance is basic. If it is low the substance is acidic. When the pH is exactly 7 the substance is neutral.
Which is the most acidic pH 2 pH 5 pH 7 or pH 11?
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
What does neutralization mean how does relate to pH?
Neutralization is a reaction between a base and an acid which forms water and a salt. This has to do with pH because whether a substance is acidic or basic is based on it's pH.
A substance has a pH of 7. Which of the following descriptions matches this pH?
A substance with a pH of 7 is not acidic nor is it basic. It is a neutral substance.
How will you classify a substance having pH value negative?
Classify a substance that has negative pH value. Foods that have acids in them is a substance hat have pH.
What would a scientist use to test the pH of a substance?
Without an advanced technical method they use pH paper for quick answer. A more accurate method is to use a pH meter.
Difference between pH of 4 and pH of 10?
The pH scale ranges from 0-14 pH. A substance that has a pH of 7 is considered to be "neutral," like pure water. A substance that has a pH less than 7 is said to be acidic, and a substance that has a pH greater than 7 is said to be basic. Therefore, the difference between those two pH levels is that the 4 pH substance is more acidic and the 10 pH substance is more basic. The more basic or acidic, the more caustic and/or corrosive the substance will be.
How does pH relate to hydrogen ion concentration?
pH = -log[H+]
You can find the pH of a substance by using?
The pH of a substance can be found by using a litmus indicator.
