no, it isn't. The acidity is a chemical change.
An acid is a chemical compound, not a physical or chemical change.
The PH is its acidity
color, odor, and acidity
Crumple is a physical change.
Aquatic Shock
Acid Shock
The pH level will start to change
Acidity itself is not a chemical change; rather, it is a property of a substance that reflects its ability to donate protons (H⁺ ions) in solution. However, when an acidic substance reacts with a base, a chemical change occurs, resulting in the formation of new products, such as water and salt. Thus, while acidity can influence chemical changes, it is not a change in itself.
False acid shock is a sudden change in the acidity of a stream or lake.
Physical
