The main use of litmus is to test whether a solution is acidic or basic. Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F).
Because each element has an exactly defined line emission spectrum, scientists are able to identify them by the color of flame they produce.
Below is the mechanism showing the hydrolysis of Iminium Ion into aldehye. The arrows are shown in RED.
N= m/v n=0.077/.200 = 0.385
