If you place the cells in the unknown solution and it shrinks/shrivels up, then the unknown solution is hypertonic. That means it has higher concentrations of permeable ions than does the cell. If the cell ruptures/bursts, then the opposite is true. In that case, the unknown solution has a lower concentration of ions (hypotonic). If nothing happens to the cell and it maintains the original morphology, then the unknown solution is isotonic and has approximately the same ionic concentration as inside the cell. These observations are based on the principle of osmosis.
What else can I help you with?
How can you determine the relative concentrations of solutions when the ratios of solute to solvent are not known?
One method is to use a spectrophotometer to measure the absorbance of the solutions at a specific wavelength and compare them. Another option is to conduct a visual comparison, looking for differences in color intensity or turbidity between the solutions. Additionally, you could perform a titration to determine the relative concentrations by observing the volume of a known concentration solution required to react completely with the unknown solution.
How do you identify if two solutions are isotonic?
Two solutions are isotonic if they have the same osmotic pressure or concentration of solutes. This means that when the two solutions are separated by a semipermeable membrane, there is no net movement of water across the membrane. Isotonic solutions have the same concentration of solutes relative to each other.

What is the relative strength of sodium chloride?
This the sum of concentrations of Cl- and Na+ ions in a given solution of NaCl.
Why do you need to calculate standard deviation and relative error?
to ensure your experiment is precise and to prevent error to happen during experiment
What information can be obtained from the total ion chromatogram in a chromatography analysis?
The total ion chromatogram in chromatography analysis provides information about the types and amounts of different ions present in the sample being analyzed. This data can help identify the compounds present and their relative concentrations in the sample.

What is logarithmic dilutions?
Logarithmic dilutions refer to a method of preparing a series of solutions where each successive dilution is a fixed ratio of the previous one, typically a tenfold (or logarithmic) decrease. For example, if starting with a concentration of 1 M, the first dilution might be 0.1 M, followed by 0.01 M, and so on. This method allows for a wide range of concentrations to be tested efficiently, particularly in microbiology and pharmacology, where it helps assess the effects of varying concentrations on organisms or reactions. Logarithmic dilutions simplify calculations and comparisons of relative concentrations.
What is relative equilibrium?
sort of trajectory, solutions of eqaution of motion of a mechanical system,
Identify this acronym:RBRVS?
Outpatient Resource - Based Relative Value Scale
When a reaction is at equilibrium is the equilibrium constant is equal to 1?
need not be..equilibrium constant is just a ratio of relative concentrations of products (multiplication of concentration in case of more than one products) to the concentration of reactants (multiplication of concentrations of reactants in case of more than one reactants)..the equilibrium concentration can be a very small number or can be a very number as well depending upon the relative concentrations of reactants and products..Unity equilibrium constants is just a special case which shows that the concentrations of products and reactants are equal..
