The objective of <em>conditioning</em> equipment is that any impurities are removed before using the glassware in the experiment.
Another reason for conditioning is that any drops left in the glassware are from the intended solution and not water, that way the concentration will not change. However this is why washing thoroughly with soap and water would defeat the purpose of conditioning. It's possible to first wash with soap and water and then rinse with vinegar, but not viceversa.
Therefore the Chlorine electron configuration will be 1s22s22p63s23p5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.
According to the equilibrium law , when of any of the reactants or the products in the reaction at an equilibrium state, is changed, then it changes the composition of equilibrium mixture in order to minimize the effect of
Acetic acid (in excess) + ⇄ + water
is a reaction which involves the equilibrium. So to force the reaction towards the side of , one of the reactant is taken in excess. All this can be explained easily by applying the equilibrium law.
