The pH of a solution is:
A. a description of the amount of sodium in medicines.
B. a general prediction of how long it will take for a substance to cause a stomach ache.
C. a measure of how fast it will denature a protein.
D. a measure of how much acid it takes to destroy a buffer.
E. a measure of the concentration of hydrogen ions it contains.
Answer (2)
The pH of a solution measures its hydrogen ion concentration, determining its acidity or basicity on a scale from 0 to 14. This is crucial in various chemical applications and biological processes. A pH below 7 indicates acidity, while above 7 indicates a basic solution. ;
The pH of a solution measures the concentration of hydrogen ions it contains, determining its acidity or basicity. The scale ranges from 0 (very acidic) to 14 (very basic), with 7 being neutral. Among the options provided, the correct choice is E: a measure of the concentration of hydrogen ions it contains.
