NEETChemistryPractical Chemistry
Given below are two statements: Statement I : Colourless cupric metaborate is reduced to cuprous metaborate in a luminous flame. Statement II : Cuprous metaborate is obtained by heating boric anhydride and copper sulphate in a non-luminous flame. In the light of the above statements, choose the most appropriate answer from the options given below.
Options
- AStatement I is false but Statement II is true
- BBoth Statement I and Statement II are false
- CBoth Statement I and Statement II are true
- DStatement I is true but Statement II is false
