1. The steeper the graph gets, faster is the change in rate. So, from the graph we can see that the rate is fastest for 0.2M because it has a greater steep, so higher rate of osmosis took place when 0.2M was placed in the solvent. On the other hand, we see a rise for 0.6M this means that the rate of osmosis was very low when 0.6M of sucrose was placed in diH2O.
2. 0.6M has the greatest slope. Its equation was 0.128x + 9.62 which was greater compared to other values. The smallest was for 0.0M where we got the equation as 0.005x + 9.88 which is the smallest compared to other values. m is the change in mass over time therefore we can see greater change for 0.6M whereas smaller change for 0.0M. This is because osmosis was more favorable for 0.6M
help give a better idea of how the rate of osmosis is affected by the
Considering the fact that Marc has both been sweating and drinking minimal amounts of water, Marc is now dehydrated. This means he has less than the required amount of water for his body to complete the processes necessary to maintain its health. As stated in the question, the process of sweating causes the loss of more water than solutes. This means that as the level of water decreases, the level of solute concentration will increase, creating a change in the water to solute ratio.
The Effect of Solute Concentration on the Rate of Osmosis Aim: To test and observe how the concentration gradient between a potato and water & sugar solution will affect the rate of osmosis. Introduction: Osmosis is defined as, diffusion, or net movement, of free water molecules from high to low concentration through a semi-permeable membrane. When a substance, such as sugar (which we will be using in the experiment we are about to analyse), dissolves in water, it attracts free water molecules to itself, and in doing so, stops them from moving freely. The effect of this, is that the concentration of (free) water molecules in that environment goes down. There are less free water molecules, and therefore less water molecules to pass across a semi-permeable membrane, through which sugar molecules and other molecules attached to them are too big to diffuse across with ease.
... : The difference in slope is positively correlated with a lower temperature. This slope becomes apparent
3. The higher the concentration of the enzyme the more there are to catalyze the reaction. Taking information from graph 1 (change in mL of enzyme), the more mL of enzymes that there are the faster the reaction rate is. It would increase until there was no substrate left available for a reaction.
The experiment is aimed at giving a better understatement of osmosis process and the different conditions in which osmosis occurs.
If the concentration of sucrose increases, then the mass of the potato will decrease. However, if the concentration of the solution in the beaker is less than that of the potato (such as distilled water), then the mass of the potato will increase. So, as the concentration of sucrose increases the rate of osmosis increases.
At point A the graph shows that no change in mass, of the potato, would have have occurred had we used a 0.2 (m) sucrose solution. This suggests that the concentration of water inside the potato would have been equal to the solution outside the potato. At point B (plain water), there is no indication that the cell is increasing in mass. This is because the cell is fully turgid and no more water can enter.
The Effects of Different Salt Solutions on Potatoes Plan My aim is to investigate how different concentrations of salt solution affect the movement of water through a partially permeable membrane (osmosis) in potatoes. Osmosis is the movement of water from a high concentration to a low concentration through a partially permeable membrane. I will add pieces of potato to varying concentrations of salt solution, wait on each solution and then record the results. I will eventually use the results to measure the percentage change in mass of the potatoes.
The graph shows the plot of average depth formed in the sand. the slope of the best fit line is.. the physical interpretation is that the increase in depth caused by the different mass balls was.. the height at which the ball was released was.5 meters although sometimes the balls were dropped slightly below or higher than the.5 meter marking causing an accuracy of +.03cm but for the purpose of the experiment i used.5 meters this next one shows the maximum and minimum slopes. the maximum slope of the graph was. and the minimum slope was..
The rate equation is in terms of concentration over time and the reaction rate compares the increase/decrease
- The nurse’s mistake will increase the saltiness due to the double amount of saline in the bag.
The gradient of the graph tells us whether the different rate curves have the same relation, meaning if they have a similar rate of reaction. Reactions can take place in a variety of customs; they can bee steep or steady. The steeper the slope, the faster the reaction takes place. The steadier the slope, the slower the reaction takes place. Aim:
Osmosis in Potato Tubes Osmosis: Osmosis is the movement of water molecules through a semi-permeable membrane from a high concentration to a low concentration. Diagram: [IMAGE] [IMAGE] Aim: To see the effects of different concentration of sugar solution on Osmosis in potato tubes. Key factor: In the investigation we change the sugar solution from: 0%-10%-20%-30%-40%-50% this is the independent variable; the dependant variable is the change in mass. Prediction: I predict that all the potato tubes in pure water or low concentration sugar solution will swell because water enters their cells by osmosis.
By analysing the results it could be seen that there was a relationship between the concentration of sodium thiosulfate and the time take for the cross to be no longer visible on the white tile through the solution. From graph 1 it could be seen that the concentration of sodium thiosulfate and the time taken for the reaction to be completed are inversely proportional, as when the concentration of sodium thiosulfate increases, the time taken decreases and the graph levels out as it approached the x-axis. Graph 2 supports this by showing that the concentration of sodium thiosulfate and the rate of the reaction share a linear relationship, meaning that the concentration is directly proportional to the inverse of the time taken.
