The pH Phosphoric acid is a non-constant value. Like other acids and alkaline compounds whose pH values are measured on a standard pH scale, the value of a given solution of the acid depends on its concentration.Continue Reading
According to Aqioin.com, pH values range from one to 14. Values below seven represent different acidic levels of acidic solutions. On the other hand, values above seven represent the alkaline levels of alkaline substances.
In respect of phosphoric acid, its acidity on a pH scale depends largely on its concentration. A highly concentrated acid solution has a lower pH value than a lowly concentrated acid solution. Strong acids have low pH values, whereas weak acids have high pH values.Learn more about Chemistry
For proper disposal of formaldehyde, a chemist or hazardous waste contractor adds chemicals, such as sodium hydroxide and hydrochloric acid, to the solution to bring the pH to a neutral level. Then, he discharges the neutralized solution to the sewer.Full Answer >
Changing the pH level can change the shape of a protein. This process is called "denaturing" the protein. When a protein becomes denatured, it does not function optimally or it does not function at all.Full Answer >
The two main conditions that cause enzymes to denature are an increase in temperature and an increase in the pH level. Enzymes work during a specific set of conditions, such as certain temperatures and pH levels, so if either are altered, they can lose their shape and ability to function.Full Answer >
Phenolphthalein, an acid-base indicator used to test the pH of a solution, turns pink due to the presence of a weak base. The indicator itself is a weak, colorless acid that forms pink anions when it dissolves in water.Full Answer >
