Simultaneous Equilibria
Several equilibria existing together in the same solution, all satisfied at once.

In depth
Every equilibrium constant, together with mass balance and charge balance, must hold simultaneously, so solving such systems generally requires numerical methods. Real solutions such as seawater or blood involve dozens of interlocking equilibria at the same time.
Examples in the real world
Blood plasma balancing carbonate, phosphate, protein and complexation equilibria to hold pH near 7.4.
