Question

You have two solutions, $A$ and $B$. The $pH$ of solution $A$ is $6$ and $pH$ of solution $B$ is $8$. Which solution has more hydrogen ion concentration? Which of this acidic and which one is basic?

• A. A $pH$ value less then $7$ indicates an acidic solution, while greater than $7$ indicates a basic solution. Therefore, the solution with $pH=6$ is acidic and has more hydrogen ion concentration than the solution of $pH=8$ which is basic.
• B. A $pH$ value less then $7$ indicates an basic solution, while greater than $7$ indicates a acidic solution. Therefore, the solution with $pH=8$ is acidic and has more hydrogen ion concentration than the solution of $pH=6$ which is basic.
  
• C. A $pH$ value less then $7$ indicates an acidic solution, while greater than $7$ indicates a basic solution. Therefore, the solution with $pH=8$ is acidic and has more hydrogen ion concentration than the solution of $pH=6$ which is basic.
  
• D. None of the above

Answer 1

The correct option is A A $pH$ value less then $7$ indicates an acidic solution, while greater than $7$ indicates a basic solution. Therefore, the solution with $pH=6$ is acidic and has more hydrogen ion concentration than the solution of $pH=8$ which is basic.

Solution $A$ with $pH=6$ is acidic in nature as it is less than $7$ while $B$ is basic with $pH=8$. The hydrogen ion concentration is more for acidic solution $A$ than the solution $B$ which is basic in nature. $A$ is an acid and $B$ is a base.
