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 is acidic and which one is basic?
A $pH$ value of less than $7$ 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.
Give two important uses of washing soda and baking soda.
Equal lengths of magnesium ribbons are taken in test tubes $A$ and $B$. Hydrochloric acid $(HCl)$ is added to test tube $A$, while acetic acid $(CH_3COOH)$ is added to test tube $B$. Amount and concentration taken for both the acids are same. In which test tube will the fizzing occur more vigorously and why ?
