net ionic equation to show that sulfurous acid, H2SO3, behaves as an acid in water.
I got this answer but do not know if it is correct.
H2SO3 + H2O --- H3O + SO
I am Not sure if its is tri/mono/diprotic
Actually I just got this question wrong because that guy was wrong. The right answer is diprotic and the equation is H2SO3 + H2O ==> H3O^+ + HSO3^-
^^^ Brittney is correct, DrBobb222 answer was wrong.
Well, you're close but not quite there! Let me help you out. Sulfurous acid (H2SO3) is actually a weak acid, and when it dissolves in water, it undergoes partial ionization. Here's the correct net ionic equation:
H2SO3 + H2O ⇌ H3O+ + HSO3-
In this equation, H2SO3 donates a proton (H+) to water, forming hydronium ions (H3O+), while the remaining HSO3- ion is formed. So, sulfurous acid is actually a diprotic acid. Keep up the good work!
To determine whether sulfurous acid, H2SO3, is a monoprotic, diprotic, or triprotic acid, we need to examine its chemical formula.
In the case of sulfurous acid, H2SO3, it consists of two hydrogen atoms (H) and one sulfur atom (S) bonded to three oxygen atoms (O). From this composition, we can determine that sulfurous acid is a diprotic acid, meaning it can donate two protons (H+ ions) per molecule in aqueous solution.
Now, let's write the net ionic equation to show how sulfurous acid behaves as an acid in water:
H2SO3 + H2O → H3O+ + HSO3-
In this equation, H2SO3 donates a proton (H+) to water (H2O), resulting in the formation of hydronium ions (H3O+) and the conjugate base of sulfurous acid, bisulfite ions (HSO3-). This net ionic equation represents the acid dissociation of sulfurous acid in water.
Therefore, your attempt at writing the net ionic equation is partially correct, but the correct representation is:
H2SO3 + H2O → H3O+ + HSO3-
Your equation isn't balanced and is incorrect.
Its diprotic because it has two H atoms that ionize.
molecular equations are
H2SO3 ==> H^+ + HSO3^- and
HSO3^- ==> H^+ + SO3^2-
but I think the question is asking just for the first one to show it gives H3O^+. The net ionic equation is
H2SO3 + H2O ==> H3O^+ + HSO4^-
