Propionic acid, C2H5CO2H (Ka = 1.34 × 10−5), is used in the manufacture of calcium propionate, a food preservative. What is the hydronium ion concentration in a 0.698-M solution of C2H5CO2H? White vinegar is a 5.0% by mass solution of acetic acid in water. If the density of wh...

As shown in the previous chapter on equilibrium, the K expression for a chemical equation derived from adding two or more other equations is the mathematical product of the other equations’ K expressions. Multiplying the mass-action expressions together and cancelling common terms, we see that: ...
The hydration caused, over time, an increase in the weight of the materials. This was evaluated through TG and DTG analyses, wherein the mass of water that was lost during heating via a TA Instrument Q600 (Centro Servizi di Ateneo per la Ricerca, CeSAR—University of Sassari) was measured...
