coul you fix my lab report?(2)?

Question

The number of unknown acid was O, and 0.1 M NaOH was used to determine molarity of unknown acid. The first step was making an unknown acid solution. About 20 mL of deionized water and 3 drops of phenolphthalein indicator were added the 5 mL acid in a flask. And then 0.1 M NaOH in a buret was slowly put into the flask. The initial volume of NaOH of both trial 1 and 2 was 10.00 mL. While small volume of NaOH was added into flask, it was swirled to mix well. Addition of NaOH was slowly continued until the red color of phenolphthalein began to linger, indicating the endpoint was being approached. When the color of solution was completely turned to red, the addition of NaOH was stopped, and the final volume of NaOH was record. The final volume of trial 1 was 27.60 mL, and the trial was 27.70mL. After getting all values, the morality was calculated by the formula, Macid ´ Vacid = Mbase ´ Vbase, and the average molarity of the acid was 3.53 ´ 10 .

Answer 1

Wow! Titration! Dont remember much of it but I do think you should pay attention in class.

Answer 2

the point of this test grow to be to income the analytical technique of acid-base titration and to apply this technique to confirm the molarity of acid in strategies the place the concentration of acid is unknown. Titration is a quantitative, volumetric technique used to confirm the concentration of a solute in a answer and is many times used to confirm the concentration of an acid or base in a answer. I only made a pair of little grammar tweaks. the belief is defined high quality! stable success with the checklist.
