australopithecus · Answer

This is a complete list of strong acid and bases it should help you to answer this question.

australopithecus · Answer

Also it is pretty important to know them all by memory for general chemistry

vera_ewing · Answer

So B?

australopithecus · Answer

is B in the table?

vera_ewing · Answer

No, A.

australopithecus · Answer

yeah I was like what D doesn't even have a hydroxide group

photon336 · Answer

@Vera_ewing NH2R is considered a strong base as well

australopithecus · Answer

That is NH4OH

vera_ewing · Answer

Is the answer A?

australopithecus · Answer

And this is a bronsted base

australopithecus · Answer

Yes you need to believe in yourself, also I gave you a link with all the strong acids and bases

photon336 · Answer

But it asks for OH- I think KOH would be safest.

australopithecus · Answer

well bronsted acids and bases

photon336 · Answer

You kind of have to know them by memory I mean Group 1 and 2 elements OH will definitely be strong bases.

photon336 · Answer

true! Also depends on your definition of a base as well
