A goal of the acid-base titration in this scenario is to determine the concentration of sodium hydroxide solution. To do this, a 1.3000 g sample of potassium hydrogen phthalate (KHC8H4O4) is massed out. The KHP has one acid proton (H+). The solid is dissolved in a beaker and 2 drops of phenolphthalein indicator is used to note an endpoint. The difference between the initial and final buret readings shows that exactly 41.20 mL of the NaOH solution is required to react with KHP. Calculate the concentration of the NaOH solution.
If anybody can explain what this is saying and walk me through it I'd greatly appreciate it.
