What is the experiment about? The experiment is about finding the time it takes for a solution of neutrase and milk to clear when using different concentrations of neutrase. Why did I choose to experiment on how the concentration of neutrase effects the time a milk solution takes to clear? I could have chosen to test how the reaction times differed at different temperatures‚ but I chose to experiment on the effect different concentrations of enzymes. The reason I did this was because I felt that

effects of hypotonic‚ hypertonic and isotonic solutions on mustard green . OBJECTIVE : To study the effects of hypotonic ‚ hypertonic and isotonic solutions on mustard green . PROBLEM STATEMENT : How does the hypotonic ‚ hypertonic and isotonic solutions affect the mustard green ? HYPOTHESIS : An increase the concentration of solutions ‚ as decrease the percentage of change in most of mustard green . MANIPULATED VARIABLE : The concentration of solution . RSEPONDING VARIABLE : Percentage of change

purpose of this lab is to find out how does the concentration of a saline solution affect the movement of the solvent molecules. Before the experiment‚ it was predicted that the saline solution in baggies would remain inside‚ without mixing with the water‚ and that the mass would not change. Throughout the experiment‚ the saline solution was added into the baggie‚ it was discovered that a small portion of the saline solution would leave the bag. In the baggie that has 0.2 percent concentration of

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

“Don’t have a boyfriend? Then you probably have acne.” One of the hidden messages the Proactiv ad sends to young girls is that if you have acne‚ you don’t have a boyfriend. Many young people struggle with acne‚ and‚ unfortunately having acne leads them to feel insecure and doubt themselves. Advertisements can encourage young people to value their looks‚ desire a significant other‚ and spend money to look beautiful and accepting by their peers. Advertisements encourage teens to focus on how they

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
