Reverse reactions and Le Chateliers principle

AI Thread Summary
In acid-base reactions, equilibrium is reached where the reaction does not proceed to completion, leading to both products and reactants existing simultaneously. To optimize yield in laboratory and industrial settings, techniques are employed to shift the equilibrium toward product formation. Le Chatelier's principle is crucial here, as it indicates that changes in concentration, temperature, or pressure can influence the direction of the reaction. In industrial processes, if a reaction does not fully convert reactants to products, the mixture is often sent to separation equipment, such as distillation columns, to purify the products and recycle unreacted reactants back into the reactor. This approach is applicable in both batch and continuous flow processes. Equilibrium stability is influenced by concentration, temperature, and pressure-volume effects, with concentration and temperature often analyzed using a 'seesaw analysis' to visualize their impact on the reaction.

TL;DR Summary
Yield in acid-base reaction low due to reverse reaction
In acid-base reactions, the reaction never goes 100% toward the product, right? A reverse reaction will occur and eventually reaction toward product and reactant will reach equilibrium. In lab/industry conditions where yield is important, how does they push the reaction toward product? I am guessing this is where Le Chatelier's principle may come in handy but I am having a hard time seeing it.
 
Chemistry news on Phys.org
In industrial processes, if the reaction does not go to completion in the reactor, the reaction mixture next goes to a piece of separation equipment (like a distillation column) where the products and reactants are purified, and the reactants are recycled to the reactor to be combined with new reactants, while the products experience subsequent processing. This applies to both batch processes and continuous flow processes.
 
You can distill/remove/precipitate (whichever works best for a given reaction) the product out to shift the equilibrium.

Generally, equilibrium stability is affected by one, two or a combination of three factors. These are concentration effects, temperature affects & pressure-volume effects. One way that is used to visualize the effect of concentration and/or temperature effects is the 'seesaw analysis'. Pressure-Volume effect follows after concentration & temperature effects.
Consider the following hypothetical reaction (A + B <=> C + D) and assume while at equilibrium it is balanced on a seesaw...

Concentration Effects can be perceived as follows ...

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
