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 ?
The fizzing will occur strongly in test tube $A$, in which hydrochloric acid $(HCl)$ is added.
This is because $HCl$ is a stronger acid than $CH_3COOH$ and therefore produces hydrogen gas at a faster speed due to which fizzing occurs.
Why should curd and sour substances not be kept in brass and copper vessels ?
Plaster of Paris should be stored in a moisture-proof container. Explain why ?
What is the common name of the compound $CaOCl_2$ ?
Why do $HCl$, $HNO_3$, etc., show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character ?
Metal compound $A$ reacts with dilute hydrochloric acid to produce effervescence. The gas evolved extinguishes a burning candle. Write a balanced chemical equation for the reaction if one of the compounds formed is calcium chloride.
