Respuesta :
pH (potential of hydrogen) is a numeric scale that is used to show the acidity or basicity of an aqueous solution. It tells how acidic or alkaline a substance is . The pH values ranges from 0 to 14, such that acidic solutions have values between 1 to 6.9 with most acidic having a pH value of 1 and those that are basic have values from 7.1 to 14, with most acidic having a value of 14. Acidic compounds contain replaceable hydrogen ions while basic compounds contain hrdroxyl ions. In this case, a coke has a pH of 3.5 (acidic) which means that it has an excess of hydrogen ions (H+) and would be called an acid.
Answer:
A coke has a pH of 3.5. this means that it has an excess of hydrogen ions and would be called an acidic.
Explanation:
The pH of the solution id the negative logarithm of hydrogen ion concentration in an aqueous solution.
[tex]pH=-\log[H^+][/tex]
- Higher the pH value lessor the hydrogen ion concentration in the solution.
- Lower the pH value higher the hydrogen ion concentration in the solution.
The pH of the coke = 3.5
[tex]3.5=-\log[H^+][/tex]
[tex][H^+]=0.0003162 m[/tex]
