Which gas is slightly soluble in water and can give a weakly acid solution of gas that is very soluble in water and can give a weakly basic solution, ammonia or carbon dioxide?

Is it carbon dioxide?
Thank you!

Have you asked two questions in one? Frankly, the way you have it states makes no sense.

CO2 dissolved in water (I wouldn't call it all that soluble) gives an acidic solution (a weak one).
NH3 gas is VERY soluble in water and gives a weakly basic solution.

No, it was one question. There should be 5 choices, but I eliminated 3 and was left with ammonia and carbon dioxide. Maybe I eliminated the wrong thing? Here are the choices: NH3,CO2,H2,O2, and H2O

Please help.
Thank you!

The choices don't bother me. It's the question that makes no sense. What about typing the question as it was given to you. Or read what you typed and see if changes need to be made. Look at it closely. It's an oxymoron.

It's really an oxymoron but that is the question...
Also, can you reply my previous post about the graph thing?
Thank you!

I give up. I can't answer a question like that. It isn't a sensible question. I'll look at the graph "thing."

Yes, you are correct. Carbon dioxide (CO2) is slightly soluble in water and can give a weakly acid solution. When carbon dioxide dissolves in water, it forms carbonic acid (H2CO3), which is a weak acid.

Ammonia (NH3), on the other hand, is very soluble in water and can give a weakly basic solution. When ammonia dissolves in water, it forms ammonium hydroxide (NH4OH), which is a weak base.

To determine which gas gives a weakly acid or basic solution, you can consider their chemical properties and the resulting products when they dissolve in water. Carbon dioxide forms carbonic acid, making the solution weakly acidic, while ammonia forms ammonium hydroxide, making the solution weakly basic.
