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)

What comes with modernization is environmental destruction‚ and thus is unavoidable for those living in modern countries. Still‚ most attention regarding overpopulation is given to third-world countries. Because of the alarming rates of child mortality and other influences‚ inhabitants of these countries resort to having many children‚ children that they often cannot provide for. The overwhelming population of

like a tired old whore that only tells you what you want to hear. You watch stories everyday about the environment and some bits on global warming and they give you some tips you can do to help Mother Earth when the major problem is obviously overpopulation. That never comes up ever. In the US‚ Al Gore has to be pressed on the issue to admit that it is a problem. People say that it’s a passing fad‚ this desire to procreate. The news knows you don’t want to hear that. The news has no problem telling

Domestic Animal Overpopulation. Do people ever think about how many stray animals are roaming the streets or in shelters? Thirty-five percent of pet owners do not spay or neuter their pets‚ so each year eight million stray animals end up in shelters each year. Only 3.5 million people adopt a pet from a shelter. The rest of the animals stay in the shelter and suffer in the cages waiting for a new home. Why do animals have to suffer in shelters‚ on the streets or in puppy mills because of irresponsible

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

Climate change is the change on the world’s climate. It is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions‚ or in the distribution of weather around the average conditions (i.e.‚ more or fewer extreme weather events). Climate change is caused by factors that include oceanic processes (such as oceanic circulation)‚ biotic processes‚ variations in solar radiation

Solution-Focused Therapy Solution–focused therapy (SFT)‚ unlike other forms of therapy argues that a person doesn’t have to understand any problem in order to resolve the problem and that the solution isn’t necessarily related to the problem. The purpose of this paper is to give a brief overview‚ description and rationale of Solution-focused therapy as well as an explanation of the therapeutic processes involved in SFT. This paper will also demonstrate through case example; systemic case conceptualization/hypotheses
