Many laboratories use 25C as a standard temperature. View Answer NH3 has a pka of around 35, so it really wants to give it's electrons to form a more stable conjugate acid (water is around pka 15.7 - orders of magnitude lower. In fact, we could make up solutions of HBr that are weaker acids than HBrO; again, the problem doesn't stipulate a concn so we must go with a "generic" which is stronger/weaker. I do not think that you are telling us the everything, but lets say that you have equal moles of KOH and Ca(OH)2.

The transformation of a solid directly into a gas is called: a.vaporization. I think it’s also easier to conceptualize that NH4 is a weaker acid than H3O, so NH3 (the conjugate base) will be a stronger base than H2O. Highest to Lowest LiCl MgO Na2O Beo Na2S, What would the net ionic equation be for : HBr (aq) + KOH (aq) = KBr + H2O, Four objects - a hoop, a solid cylinder, a solid sphere, and a thin, spherical shell - each has a mass of 4.59 kg and a radius of 0.252 m.
