There is a chemical under consideration. we do'nt know if it is HCl or H2SO4.which of following will

This sort of question is answered by general knowledge. That is to say you figure it out once and remember the answer so you don't ever have to figure it out again.

HCl and H2SO4 are strong acids, meaning they dissolve 100%. "Strong" has nothing to do with concentration or corrosiveness. There are seven strong acids:
Sulfuric
Nitric
Hydrochloric
Chloric
Perchloric
Hydrobromic
Hydroiodic

It's easy to remember the list because there are three of the most common industrial acids, three "chloric" acids, three "hydro" acids, and they all make a clumsy "7" on the periodic table.

There are dozens of strong bases and hundreds of "almost strong" bases.

Now you look at your list and recall from general knowledge that all nitrates are soluble, and so is table salt. So when you mix this stuff you have a cloud of dissociated ions swirling around, bumping into each other. Maybe two hydrogen ions meet, but they repel strongly because they are both positively charged, so nothing happens. Maybe a lithium ion meets a chloride ion and for a moment you have lithium chloride. So you look that up someplace and find that it is soluble. That means the product does not last. Eventually you learn that silver will combine with any source of chloride ions and precipitate instantly. But you also learn that silver sulfate is "minimally" soluble, so you might have to take some more care in performing your test.

Always research your chemicals before you start. For example, silver will dissolve in aqueous ammonia and the result is explosive, but not until it has dried and you try to wash the glassware. You do not want to learn such things by accident.

BTW: You said "conforms" when you meant "confirms". You can not stand mistakes in this subject. Mistakes kill people. In chemistry you have to be pretty darn good to do the work at all.
