Abstract In this experiment‚ the Ksp for calcium sulfate dihydrate‚ CaSO4·2H2O‚ by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA‚ H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however‚ is 3.14 x 10-5. A percent

Buffer solutions and common ion effect A buffer solution resists (or buffers) a change in its pH. That is‚ we can add a small amount of an acid or base to a buffer solution and the pH will change very little. How to calculate pH of buffer solution containing both acid and conjugate base? Dissociation constant definition 1.1 can be rearranged into or (note that due to sign change [A-] was moved to nominator). This is so called Henderson-Hasselbalch equation (or buffer equation)

An investigation to find the water potential of potato and carrot tubers in a sucrose solution‚ of concentration 0.00 – 0.50Mol‚ over a 24 hour period Interpretation Written Communication C1 From our graph it can be seen that the concentration of sucrose solution is 0.18 M at 0% change in mass for the potato and 0.355 M at 0% change in mass for the carrot. I will use these values to find the solute potential by using the calibration graph. I will work out the water potential by using the

culture and personality. Benedict studies different cultures such as the Zuni tribe and the Dobu Indians. Each culture she finds is so different and distinctive in relation to the norm of our society. Each difference is what makes it unique. Benedict compares the likenesses of culture and individuality‚ "A culture‚ like an individual‚ is a more or less consistent pattern of thought or action" (46)‚ but note‚ they are not the same by use of the word‚ "like." Benedict is saying that figuratively

is doing the writing this version of history also paints our assessment of these heroes and villains. Sometimes the deeds that make one man a villain are given more weight than deeds that might deem the same man a hero. That is what happened to Benedict Arnold‚ his actions during the American Revolutionary War ensured victory for the American forces. But his acts of heroism have since been overshadowed by his final act of betrayal. When we think of the American Revolutionary War we have a tendency
