(6 + 1/4)·4 = (6·4) + (1/4·4) = 24 + 1 = 25

Or, you can convert the mixed number to the improper fraction 25/4 and then multiply by 4 to get 25.

A substance is tested and has a ph of 7.0. how would you classify it? a. a strong acid b. a strong base c. a weak acid d. neutra

Eddi Din [679]

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.
