A substance is tested and has a Ph of 7.0. It would be a weak acid.
The correct option is (c) a weak acid .
What is the nature of substance if the pH is less than 7?
- Acidity is defined as pH below 7. More than 7 pH is considered basic.
- Each whole pH number below 7 is ten times more acidic than the next higher value since the pH scale is logarithmic.
- For instance, pH 4 is 100 times (10 times 10) more acidic than pH 6, while pH 5 is ten times (10 times) more acidic than pH 4.
What is pH?
- The pH scale determines how acidic or basic water is.
- The range is 0 to 14, with 7 representing neutrality.
- Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
- In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.
