Solve the acid-base or equilibrium problem in {equilibrium_problem} by tracking the dominant species at each stage. (1) Identify every species present and classify the system: strong or weak acid/base, buffer, or a titration at a specific point — the classification selects the method, and treating a weak acid as strong (or ignoring that a salt hydrolyzes) is the recurring error. (2) Write the relevant equilibrium reaction(s) and equilibrium constant expression(s), and note which equilibrium dominates so you don't solve a negligible one. (3) For a titration, determine where you are on the curve — before equivalence (excess titrated species, often a buffer), at equivalence (the salt controls pH, which is not necessarily 7), or past it (excess titrant dominates) — because each region needs different arithmetic. (4) Set up the ICE table (initial, change, equilibrium) and solve, checking whether the simplifying approximation (x small relative to initial concentration) is valid rather than assuming it. (5) Compute the target — pH, concentration, or volume — and verify the approximation held; if not, solve the full quadratic. (6) Sanity-check: does the pH fall on the correct side of neutral for the chemistry, and does it move the right direction as titrant is added?
