Question

Ions of an element of group 1 participate in the transmission of nerve signals and transport of sugars and aminoacids into cells. This element imparts yellow colour to the flame in flame test and forms an oxide and a peroxide with oxygen. Identify the element and write chemical reaction to show the formation of its peroxide. Why does the element impart colour to the flame?

Long Answer

Solution

The element imparts yellow colour to the flame in flame test which means the element of group 1 is sodium. Sodium is used in the transmission of nerve signals and transport of sugars and amino acids into cells. Reactions are shown below.

\[\ce{2Na + O2 -> Na2O2}\]

\[\ce{4Na + O2 -> 2Na2O}\]

\[\ce{2Na2O + O2 -> 2Na2O2}\]
