solution can be determined (so long as one value’s is known) using titration. In this case though‚ finding the molarity of the acid used in the reaction is then used to determine the percent of that acid in a vinegar solution and compared to the standard value for % acid present in vinegar. The second part of the experiment was to see if by titrating a solution of NaOH and an unnamed mystery acid‚ you could find the molar mass of the unknown acid (solving the mystery). It must be understood that

Apple cider vinegar contains an acidic which helps in the reduction and spreading of fungal infections. In this home remedy simply mix equal parts of water and apple cider vinegar into a large bucket or foot bath tub. You then soak the infected nails or toenails in the mixture. Make sure that your

step in the actual experiment is to open the two packages containing the polymer creatures and then placing each of them aside for later. Next‚ fill the the two containers with the two different liquids of choice‚ which in this case is water and vinegar. Finally‚ after filling the containers‚ place one of the two polymer creatures in each of the containers. Also‚ be sure to record the results throughout the day as the creatures soak in each liquid and to observe all of the effects that each liquid

Chapter 1 The Problem and the Background of the Study A. Introduction One of the major problems in our country is energy shortage. There are many methods and proposals on how to conserve it such as the use of batteries. One of these is an electrolytic cell. It contains an electrolyte through which an externally generated electric current is passed by a system of electrodes (electrically positive electrode is called the anode and the negative electrode the cathode) in order to produce an electrochemical
