Answer:
Acid end
Explanation:
The acid end of the pH scale contains solutions that have the most hydrogen ions.
- A convenient scale for expressing the level of acidity or alkalinity of aqueous solutions is the pH or pOH scale .
- The pH of a solution is the negative logarithm to base 10 of the hydrogen ion concentration in the solution.
- The scale ranges from 1 to 14
- 1 is the lower limit and 14, the upper limit
- Acidic solution has a pH value less than 7.
- As pH decreases the hydrogen ions concentration increases.
- Neutral solutions have pH of 7
- Basic solutions have pH greater than 7.
