if the reactant solution is used to write on a piece of paper and the paper is allowed to partially dry, what can be done to bring out the colored writing

Expose the paper to the atmosphere or moisture

Explanation:

An interesting experiment that demonstrates the equilibrium of complexes is that of the invisible ink.

The invisible ink is pink colored [Co(H2O)6]Cl2 which is essentially colorless and pale when it is used to write on paper. This complex is almost colorless when dilute. Therefore, when it is used in writing, the writing can not be seen.

However, if the paper is left to stand or allowed to absorb moisture; the following equilibrium is set up:

[Co(H2O)6]Cl2 ⇄ [CoCl2(H2O)2] + 4H2O

The formation of blue [CoCl2(H2O)2] on standing or exposure to moisture enables the colored writing to be easily read.

to be fair, you have to have a very high iq to understand rick and morty. the humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. there's also rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from narodnaya volya literature, for instance. the fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about life. as a consequence people who dislike rick & morty truly are idiots- of course they wouldn't appreciate, for instance, the humour in rick's existential catchphrase "wubba lubba dub dub," which itself is a cryptic reference to turgenev's russian epic fathers and sons. i'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as dan harmon's genius wit unfolds itself on their television screens. what fools.. how i pity them.

and yes, by the way, i do have a rick & morty tattoo. and no, you cannot see it. it's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 iq points of my own (preferably lower) beforehand. nothin personnel kid
