$\begingroup$ And apparently, the text comes from India's National Council for Educational Research and Training! So ironic! Thanks for clearing me up on that one, really helpful. And sorry for I could not receive the notifications earlier. $\endgroup$

$\begingroup$ @Rew, Sorry to say but India's National Council for Educational Research and Training has to update itself. They have many outdated things. I see questions on chemical equivalents and n-factors here on these forums which were taught in the 1940s. $\endgroup$

$\begingroup$ Yes I agree. As an ex-user of NCERT, I have regretted studying from it and all I can say is that the textbooks are full of errors and misleading information which has to updated. $\endgroup$

$\begingroup$ @Nilay Ghosh, being outdated in syllabus was probably forgivable when internet did not exist. Today NCERT should see what is being taught around the world and compare the course contents and update them. There is a saying which is roughly translated as "If we lay the first brick of wall incorrectly, and if that wall reaches the stars, it will remain tilted." Therefore science at the school level has to improve so that students take interest in science from the beginning and better scientists can be produced at the university level. $\endgroup$

$\begingroup$ @AdilMohammed, Yes you are right. If enough heat were provided one would see atomic emission not molecular compound emission of low temperature flames. $\endgroup$
