Rob Plant + 2,635 RP January 12 Alkalinity (from Arabic: القلوية, romanized: al-qaly, lit. 'ashes of the saltwort')[1] is the capacity of water to resist acidification.[2] It should not be confused with basicity, which is an absolute measurement on the pH scale. Alkalinity is the strength of a buffer solution composed of weak acids and their conjugate bases. It is measured by titrating the solution with an acid such as HCl until its pH changes abruptly, or it reaches a known endpoint where that happens. Alkalinity is expressed in units of concentration, such as meq/L (milliequivalents per liter), μeq/kg (microequivalents per kilogram), or mg/L CaCO3 (milligrams per liter of calcium carbonate).[3] Each of these measurements corresponds to an amount of acid added as a titrant.

Wondering if you ever try to shake a co2 fire extinguisher? Any sound of liquid produced? Even if yes, once used, the critical point of pressure and temperature change will cause mainly gas remains inside? I refer you to the phase diagram I previously posted. The CO₂ in a full class B fire extinguisher is a liquid at cooler temperatures. At warmer temperatures, it becomes a supercritical fluid. The main characteristic of a supercritical fluid is its combination of gas-like and liquid-like properties. Unlike a typical gas or liquid, a supercritical fluid exists at a temperature and pressure above its critical point, where the distinct boundaries between the two phases disappear. There is no phase boundary to "slosh". Once it is released via the extinguisher's "horn", the supercritical fluid flashes to a gas immediately.
