Q: Although Lactated Ringers (LR) has PH of 6.5, it is an alkalizing solution. How?


Answer: Although LR has pH of 6.5, it is an alkalizing solution.

The lactate in LR is metabolized into bicarbonate (HCO3-) by the liver. Though lactate itself contributes a strong anion, lactated Ringer's solution alkalinizes via the sodium cations it leaves behind. They increase the strong ion difference in solution, leading to proton consumption and an overall alkalinizing effect.
