When dissolved in water, what does acids produce?

Answer 1

Ellie Andrews

By definition, acids produce hydronium ions............

Take any acid and dissolve it in water to cause the following equilibrium reaction to happen:

#HA(aq) + H_2O(l)rightleftharpoons H_3O^(+) + A^(-)(aq)#

The given equilibrium operates farther to the right the stronger the acid.

And, #K_a#, #"the acid dissociation constant"# operates:

#K_a=([H_3O^+][A^-])/([HA])#

Clearly, the stronger the acid, and the higher the value of #K_a#, the farther to the right the given equilibrium operates.

Strong acids, #H_2SO_4#, #HX (X=Cl, Br, I), HNO_3, HClO_4# give equilibria that are strongly to the right. Capisce?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
