write the Ph of acid
Answers
Explanation:
The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.
Acids have pH values lower than 7.
Explanation:
pH is a scale used to specify how acidic or basic (or alkaline) a water-based solution is, in chemistry. Acidic solutions have a lower pH value, while basic solutions have a higher pH value. At room temperature (25°C or 77°F), pure water is neither acidic nor basic and has a pH value of 7.
The pH scale ranges between 1 and 14. Acids have pH values lower than 7. Bases have pH values higher than 7. Neutral substances have pH values approximately equal to 7 (Water).
To calculate the pH of an acid, you need to know the concentration expressed in molarity (mol HCl/L solution). We use the following equation to find the pH.
pH = -log[H+]
This means that we take the negative log of the hydrogen ion concentration to find the pH.
