WitrynaIntroduction. Serum total calcium (T Ca) is made up of three fractions of calcium ions in equilibrium with each other (1,2).The physiologically active fraction (~50%) consists of solvated calcium ions and is commonly referred to as the ionized calcium (I Ca) fraction.Its concentration is regulated, with a typical reference range of 1.15–1.29 … Witryna30 sty 2024 · STEP 4: Use the ICE table to calculate concentrations with K a. The expression for K a is written by dividing the concentrations of the products by the concentrations of the reactants. Plugging in the values at equilibrium into the equation for K a gives the following: K a = x 2 0.150 − x = 1.6 × 10 − 2.
