Given below are two statements : Statement I : Upon heating a borax bead dipped in cupric sulphate in a luminous flame, the colour of the bead becomes green. Statement II : The green colour observed is due to the formation of copper(I) metaborate In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth Statement I and Statement II are false
- BBoth Statement I and Statement II are true
- CStatement I is false but Statement II is true
- DStatement I is true but Statement II is false
Correct answer
A. Both Statement I and Statement II are false
Step-by-step solution
