Acid and vinegar lab
The process is complete for the acid and vinegar lab. To start out we had to titrate the acid KHP (which is not just K, H, and P). To do this we had to set up the lab by clearing out the burett and filing it with NaOH (base). Taking .5ish grams of KHP and dissolving it in a about 75 ml of water with a couple drops of phenolphaline. Taking the KHP in a flask and put it under the burett to get titrated (make the phenolphaline turn the liquid light pink). Then you take the flask and fill ti with 10 ml of vinegar and then titrate it with the leftover base in the burett. After doing all of this we can find a large amount of different numbers and items. Such as the molarity of the base or the atomic mass of vinegar.
