A cell that is 35 percent water is placed in a solution that is 35 percent water Which way will the net movement of water go?
If the cell and the solution contain the same percentage of water, the solution is isotonic. This means that the net movement of water will not be in either direction, there will be no net movement.
Can you briefly discuss the difference between a concentration gradient and concentration difference?
A concentration gradient refers to the gradual change in concentration of a substance over a distance, while a concentration difference simply indicates the variation in concentration between two points. In essence, a concentration gradient describes how the concentration changes across a space, whereas a concentration difference highlights the contrast in concentration between specific locations.
What is the difference in the concentration of a substance across a space is called concentration?
The difference in concentration of a substance across a space is called a concentration gradient. It represents the change in concentration over a given distance and drives processes like diffusion and osmosis. Substances move from areas of high concentration to areas of low concentration along the concentration gradient to achieve equilibrium.
Describe the concentration gradient shown in the transparency?
The description of the concentration of a gradient shown in the transparency is a gradual change of solutes that are in a solution. This is a function of distance through the solution in biology.
What is the continuous movement of particles but no overall change in concentration?
This is known as diffusion. Diffusion is the process by which particles move from an area of higher concentration to an area of lower concentration, leading to a uniform distribution of particles.
What is the change in hydrogen ion concentration when the pH decreases by 3 units?
The change in hydrogen ion concentration is a 1000-fold increase when the pH decreases by 3 units. This is because the pH scale is logarithmic, with each unit change representing a 10-fold change in hydrogen ion concentration.
What does a change in pH of one unit represent in terms of hydrogen ion concentration?
A change in pH of one unit represents a tenfold change in hydrogen ion concentration. For example, a solution with a pH of 4 has 10 times higher hydrogen ion concentration than a solution with a pH of 5.
Ph solution by 2 numbers change in hydrogen ions by?
The pH scale is logarithmic, meaning each change of one unit represents a tenfold change in hydrogen ion concentration. For example, a change of 2 in pH corresponds to a 100-fold difference in hydrogen ion concentration. An increase in pH by 2 indicates a decrease in hydrogen ion concentration, while a decrease in pH by 2 indicates an increase in hydrogen ion concentration.
When the pH in a stomach increases from 2 to 4 How does the hydrogen ion concentration change?
When the pH in a stomach increases from 2 to 4, the hydrogen ion concentration decreases by a factor of 100. This is because the pH scale is logarithmic, with each unit change representing a tenfold difference in hydrogen ion concentration.
How is a change in hydrogen ion concentration reflected in the pH?
pH is the negative logarithm of the hydrogen ion concentration; so an increase in hydrogen ion concentration give a reduction in pH. A reduction in hydrogen ion concentration causes an increase in pH.
Change 6.3 to an equivalent percent?
6.3 = 630% (multiply a number by 100 to get its percent equivalent).
What is a pH table?
The pH of a solution measures the hydrogen ion concentration in that solution. A small change in pH represents a large change in hydrogen ion concentration. For example, the hydrogen ion concentration of lemon juice (pH of 2.3) is 63 times greater than that of tomato juice (pH of 4.1), and 50,000 times greater than that of water (pH of 7.0). mustki2005@yahoo.comNigerian
Why does the percent ionization of acetic acid increase as the concentration of the solution decreases?
As you increase the concentration of the solution, the concentration of H+ does not change. Meaning, the concentration ionized does not change. Just the original concentration increases. Since percent ionization = (concentration ionized)/(original concentration) , and the original concentration is increased, the percent ionization therefore decreases.
Is the concentration in pH of 4 higher or lower than the concentration of pH of 6?
The concentration of a solution at a pH of 4 is higher in hydrogen ions than a solution at a pH of 6. pH is a logarithmic scale of hydrogen ion concentration, so each unit change in pH represents a 10-fold difference in ion concentration.
How much does the concentration change each time the pH changes one spot?
The concentration changes by roughly a factor of 10.
How much greater is the hydrogen ion concentration in tomatoes 4.2pH then in rainwater 6.2pH?
The hydrogen ion concentration in tomatoes at pH 4.2 is 100 times greater than in rainwater at pH 6.2. pH is a logarithmic scale, so each whole number change represents a tenfold difference in hydrogen ion concentration.
How do you change 6.6 percent to decimal?
Divide percent by 100 to get the equivalent plain old number. 6.6 percent = 0.066
