Equation Balancing with Subsalicylate
This has been pestering me for ages, cannot seem to work it out . . .online equation balancers seem to be no good either.
C7H5BiO4 + HCl --> BiCl3 + C7H6O3
I thought that perhaps it had something to do with that the bismuth subsalicylate starting product has no confirmed formula .. . it's exact structure
is apparently not known.
Help?

That equation can't be balanced. It's some simple algebra. The first three
coefficients must be as thus, balancing BiCl3: x * C7H5BiO4 + 3x * HCl --> x * BiCl3 + y *
C7H6O3. Balancing C, we get 7x = 7y, implying x = y. Balancing H, we get the relationship 5x + 3x = 6y, which is
consistent with balanced C only if x = y = 0. Balancing O, we get 4x = 3y, which is non-trivially consistent with balanced H but not with balanced C.
So you're missing either some reagents or products, or both, or need to start over.

While the structure may be a large cluster, the simple molecule is good enough for rough stoichiometry.
Inspect the <b>simplified structure</b> at wikipedia.
There is an OH ligand on the Bi that protonates, then leaves as water.
So to amend the equation, <b>add water.</b>
C<sub>7</sub>H<sub>5</sub>BiO<sub>4</sub> + 3(HCl) --> <b>H<sub>2</sub>O</b> +
BiCl<sub>3</sub> + C<sub>7</sub>H<sub>6</sub>O<sub>3</sub>

Thanks a lot arsphenamine and watson, you may have guessed that I am extracting bismuth from pepto-bismol
