According to the Bronsted- Lowry definitions a acid is a proton donor(H+), while a base is a proton receiver(H+). Acid-Base equations typically have one major thing in common and this is water. We get water because a acid contains a H+ ion while bases contain OH- ion, when the two are combined they react and create water. This happens in titration, usually either a base or acid is neutralized by by an acid or base intill the solution is water and neither acidic or basic. This is usually done by dripping a base into an acid or acid into a base through a buret, the process is complete once the indicator in the solution being dripped into is barely noticeable. Titration allows scientist to figure out unknown molaritys of acids or bases. In our lab we followed this process with HCl and NaOH. We used an unknown amount of HCl to titrate 20 mL of 1mol NaOH. The first trial took 23mL of HCl to neutralize the NaOH the second trial took 20mL to neutralize the NaOH. We take the average of the two trials which were 20mL and 23mL and input into them into an equation. The math is done as so to figure out the unknown molarity of the HCl:
Which comes out to a .935 average Molarity.
