can anyone help me with my homework??thank you Preparation of Vanadium (V) standard. 1.25g of vanadium (V) oxide was weighted into 200 ml beaker. Then, 2.0 g of Naoh pellets followed by 100ml of distilled water was added. The beaker is gently heated until the entire solid dissolved. I 50.0 ml of distilled water was added after that. 2N of sulphuric acid was added until the solution just becomes acidic. The colour of the resulting solution will be yellow. a)...
