Titration Of Acids And Bases Lab Answers

The moles of acid will equal the moles of the base at the equivalence point. When the color changes to the specified color, the titration has reached endpoint. A good indicator for a specific acid-base titration has an endpoint with a pH at or near the pH of the equivalence point. However, both strong acids and strong bases can be very dangerous and burn your skin, so it is important to be very careful when using such chemicals. Titration is a procedure of careful addition of one solution to another solution a little at a time until a specificend point is reached. To reveal the end point of the titration we use an acid/base indicator in this example it is phenolphthalein. When the reaction was complete, the number of moles of base used equals the number of moles of acid originally present; knowing the number of moles of acid allowed you to compute the concentration of acid in the vinegar sample. To find the number of moles of acid. Because the pH of a neutral solution is 7, an indicator that changes color near this pH should be used for an acid-base titration. In an acid-base titration, the neutralization reaction between the acid and base can be measured with either a color indicator or a pH meter. How do you find the molar mass of an unknown acid if you know the weight of the sample (in grams) and the volume of the solution (250mL)?
