<u>A substance is tested and has a </u><u>Ph of 7.0</u><u>. It would be </u><u> a weak acid. </u>
<u>The correct option is </u><u>(c) a weak acid .</u>
<u></u>
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.

Your answer will be negative 96
You can use the point-slope form of a line to do this, but because there is zero slope, that's like using a chainsaw to cut a piece of paper.
Lines with zero slope are horizontal and the only thing that changes is the x-coordinate. The y-coordinate stays the same no matter what. Our y coordinate above is 2, and we report that as our equation of the line.
The equation is y = 2.
