if we put milk/coffee/milo in silver coated flask/thermos, is there any chemical reaction occur between the silver coated and the liquid put in it?
would it be safe to use it after that?

One reason why gold and silver are used for jewelry is that these metals are not very chemically reactive, and thus, do not tarnish.
A silver-colored thermos is usually stainless steel. That's also a metal that is not very chemically reactive.
The liquid, however, doesn't normally come in contact with that, but with the glass liner. The glass liner will have a mirror finish but like any good mirror, the silvering is applied to the back side of the glass. Glass is not *completely* nonreactive; but it's probably better than any other food container you can name.
Coffee contains oils. You will want to wash the thermos *very* thoroughly between uses in order to remove those oils, as they are particularly hard to remove. They will turn rancid and spoil the taste of whatever you put into the thermos next. Milo is a milk-based beverage, and with it or milk, you would run the risk of the milk souring, but an average cleansing of the thermos would be adequate.
Milo is an Australian drink, so I assume you're from Oz. In that case, "no worries, mate!"

If you are talking of a thermos, the silver coating is on the inner surface of the glass. So, the silver doesn't come into contact with the liquid and glass is chemically inert for most of the household liquids.
Even silver is not much affected.

The thermos flask is made by utilising plastic and steel glass and that they use silver color to color because of the fact the warmth or chilly gadgets stored in the flask will proceed to be at around comparable tempature because of the fact the silver color can not obsurpe the warmth and chilly temparatures and it will reflects the warmth or chilly into interior it so the drink stored in thermos flask retains at consistent temparature for long term the place as in yet another flasks it won't consistent

should not be a problem.
Sterling silver cream pitchers have been used for centuries.
Make sure you clean it out well though... milk is slightly acidic and would promote corrosion.

No. It will be perfectly safe.
