From The Harbinger‚ an 1830’s newspaper Female Workers of Lowell (1836) We have lately visited the cities of Lowell [Mass.] and Manchester [N.H.] and have had an opportunity of examining the factory system more closely than before. We had distrusted the accounts which we had heard from persons engaged in the labor reform now beginning to agitate New England. We could scarcely credit the statements made in relation to the exhausting nature of the labor in the mills‚ and to the manner in which the

Determining the equilibrium constant from pH values of changing concentrations of ethanoic acid Design Research question: How will altering the concentrations of ethanoic acid affect the pH value‚ and‚ in-turn‚ the equilibrium constant? Background information: When weak acids react‚ the reaction typically does not go to completion. Rather‚ the system goes to an intermediate state in which the rates of the forward and reverse reactions are equal. Such a system is said to be in chemical equilibrium

AP U.S. 1/28/14 DBQ Between 1875 and 1900‚ there were organized labor forces popping up left and right‚ and the purpose of all of them was to improve the common workers position. However‚ few of these unions managed to bring much of a positive change. At the time‚ the three most influential labor forces were the Knights of Labor‚ who fell from power before they could bring much change‚ the American Federation of Labor‚ who didn’t fare any better‚ and the Populist party‚ who could be seen as the

to determine the molarity of NaOH‚ we rinsed a burette with about 5ml of water and another 5ml of NaOH to prepare it for the experiment. We then measured exactly 25ml of the prepared KHP from the previous part into a 250ml Erlenmeyer flask and added 2 drops of the indicator‚ phenolphthalein. Next we filled the burette with the approximately 0.1 M NaOH so that our initial volume will be 0.0mls. We then started our titration by carefully pouring a little amount of the base into the prepared 25ml of
