L of Pirate Purple dye solution. The claim states that the use of the concentration and absorbance of the Blue 1 dye and Red 3 dye will lead to the concentrations of the red and blue dye to yield 1 L of Pirate Purple dye. In order to understand molarity or concentration, familiarity with the terms of solute, solvent, and solution are very important. A Solute is a substance that is being dissolved by a solvent. A solvent is a substance that is dissolving the solute. Solution is a solute of a homogenous

42. For each of the following mixtures, explain whether it is a solution or a heterogeneous mixture. For the solutions, identify the solute and the solvent. a) Cloudy pond water – heterogeneous mixture, this is because it is cloudy, solute is dirt particles - in the water there is clay and humus. b) Apple juice - is a homogeneous solution, water is the solvent there are organic acids, sugars and gums c) Rain water – is a homogeneous mixture, rainwater is nearly a distilled water. The mixture is

"Do different concentrations of solutions determine the mass of a potato?" Introduction: The way to get the full results of this lab was through the process of osmosis. Osmosis is the movement of water across a membrane into a more concentrated solution to reach an equilibrium. When regarding cells osmosis has three different terms that are used to describe their concentration. The first of these words is isotonic. Cells in an isotonic solution show that the water has no net movement and the amount

〖Co〗^(2+)in a Mixture Natalia Nole Last updated: September 12, 2016 Purpose Let’s assume that we have two solutions, a clear and a colored one, whose concentrations and identities are unknown. If we shine some light of some intensity towards them; some of this light will go through and some of it will be absorbed. This is important because based on the amount of light absorbed by the solutions we can calculate their concentrations. This important and simple principle is known as Beer’s Lambert law;

of Potato Cells in Various Salt Solutions Introduction I have been asked to investigate the effect of changing the concentration of a solution on the movement of water into and out of potato cells. I will be able to change the input of my experiment. The input variable will be the concentration of the solution. The 100% solution is sodium chloride dissolved in water (salt water). This will be referred to as the 100% solution from now on. But the type of solution is not important as Osmosis is

Concentrations of Salt Solutions Introduction: Osmosis is the movement of water molecules across a partially permeable membrane from a region of high water potential to a region of low water potential. It can be affected by several different variables including concentration of salt solutions. When a plant cell is put in pure water it will become turgid and it will not burst due to the presence of a cell wall and a large permanent vacuole and when it is put in a concentrated solution it will be plasmolysed

Refining Solution Problem As with any other major purchase, to be satisfied, a person must invest time and determination to identify the best opportunity before handing over his or her hard-earned cash. You haven’t divulged the particulars of your situation or budget, but there are some general guidelines to keep in mind. In this paper, the individual will discuss the original issues, initial solution, and the critical examination of the best solution. Also do an evaluation of the argument and revise

rate of osmotic pressure between tap water and surcose solutions. This will happen by using different concentrations of sucrose (20%, 40%, 60%) afterwards, the change in mass ratio would be observed over time. Other factors affect the rate of osmosis, factors like, pH, Temperature and also pressure. Hypothesis: With predictions, the dialysis bag acting as a semi-permeable membrane in the prescence of sucrose solution, where the water potential is high would cause the mass

sucrose solutions. Osmosis is the process, in which, water moves across a differentially permeable membrane. The eggs were soaked in vinegar to remove the outside hard shell but still leave the egg in its membrane. By placing the six de-shelled in different sucrose solutions, we tested the rate of osmosis. The eggs were placed in the solutions for an hour and weighed in fifteen minute intervals. Then, each weight was recorded and graphed. The results showed that the egg in the water solution gained

pH is a measure of the concentration of the H3O+ ions in a solution, and buffers are solutions that resist changes in the pH when an acid or an alkali is added. The objective of this lab was to determine the ways in which a buffer could effect changes in pH of a solution. This was done through titrations of phosphate solutions, acidic HCl, and basic NaOH, with distilled water. The intent was to note the changes caused by the buffer by observing the buffering range and buffering capacity from the
