ICE Table Solver

For the dissociation A ⇌ B + C, set the initial [A] and the equilibrium constant K. The table fills the Initial / Change / Equilibrium rows and the x-algebra is solved step by step.

A(aq) ⇌ B(aq) + C(aq) K = [B][C] / [A]

initial [A]₀ 0.50 M

equilibrium K

	A	B	C
I (initial)		0	0
C (change)	−x	+x	+x
E (equil.)

Try: push K small (< 10⁻⁴) and watch the "small-x approximation" turn valid (x ≪ [A]₀); then crank K toward 1 and see it break the 5% rule, so you must solve the full quadratic.
