How do you find the concentration of potato cells immersed in salt solutions?
You would have to use a spectrophotometer to measure the absorbance of your unknown solution. But first, you need to make several solutions with known concentrations. Measure the absorbance of the known concentrations and plot them on an X and Y axis where X equals concentration and Y equals absorbance. Do a best-fit line for your data. Measure the absorbance of your unknown solution. Find this value on your Y-axis and find out where this value intersects with your line of best fit. The X value at the intersection is your concentration of potato cells. By the way, make sure you use the same wavelength throughout the experiment.
What is The process of adding a known amount of solution of known concentration to determine the concentration of another solution is called?
titration is the best method to determine the unknown concentration of the unknown. if ur known is a solid then you would have to used distilled water to ensure it is submerged before you titrate.
How calibration curve is obtained using flame spectrophotometer?
A calibration curve for a flame spectrophotometer is obtained by measuring the absorbance of a series of standard solutions with known concentrations of the analyte. The instrument records the absorbance values at specific wavelengths. By plotting the absorbance against the concentration of the standard solutions, a linear calibration curve is achieved. This curve can then be used to determine the concentration of an unknown sample based on its absorbance value.
What is external calibration and is it the same as the manual calibration of equipment?
Well, external calibration is a method used in analytical chemistry to determine the concentration of an unknown analyte. In essence, you take known concentrations of the analyte and plot it on an absorbance or transmittance graph to get a linear plot. And then you take that linear equation and plug in the absorbance or transmittance value received from the unknown solution and get the concentration. An example of this is if you want to find out the amount of calcium in a vitamin tablet. Dissolve the vitamin tablet and test the solution to get an absorbance value. Then test by the same method various concentrations of a calcium solution, plot this on a graph of absorbance vs. concentration and there yah go.
What is a standard solution?
A standard solution is a solution of known concentration that is used to determine the concentration of an unknown solution in a chemical analysis. It is often prepared by accurately measuring a known amount of solute and dissolving it in a known volume of solvent.
How do you determine the colorimetric estimation of unknown copper sulphate concentration in solution?
To determine the colorimetric estimation of unknown copper sulfate concentration in solution, you can use a colorimetric method such as a complexation reaction with a specific reagent that forms a colored complex with copper ions. By measuring the absorbance of this colored complex at a specific wavelength using a colorimeter, you can correlate the absorbance values to known copper sulfate concentrations to determine the concentration of the unknown solution. Calibration curve plotting absorbance against known concentrations is commonly used in colorimetric estimations.
How can you calculate absorbance of unknown from linear equation?
To calculate the absorbance of an unknown sample using a linear equation, you first need to establish a calibration curve by plotting the absorbance values of known standards against their concentrations. The resulting linear equation, typically in the form (y = mx + b), relates absorbance (y) to concentration (x), where (m) is the slope and (b) is the y-intercept. By measuring the absorbance of the unknown sample and substituting this value into the linear equation, you can solve for the concentration of the unknown sample. This allows you to determine the absorbance based on its concentration derived from the calibration curve.

What is titration technique?
Titration is a laboratory technique used to determine the concentration of an unknown solution by reacting it with a solution of known concentration. A burette is used to carefully add the known solution to the unknown solution until a chemical reaction reaches completion, indicated by a color change or other observable signal. The volume of the known solution added is used to calculate the concentration of the unknown solution.
What is titrate?
Titrate is a process used in chemistry to determine the concentration of a substance in a solution. It involves slowly adding a solution of known concentration (titrant) to another solution until a reaction is complete, allowing the concentration of the unknown substance to be calculated.
What is meant by titrant in titration?
In titration, the titrant is a solution of known concentration that is added to the analyte (solution of unknown concentration) to determine its concentration. The titrant reacts with the analyte in a chemical reaction, allowing for the determination of the analyte's concentration based on the volume of titrant required to reach the equivalence point.
What type of reaction would a titration be useful for?
A titration would be useful for determining the concentration of an unknown solution by reacting it with a known concentration of another solution. This process is commonly used in acid-base reactions, where the point of neutralization is reached to determine the concentration of the unknown solution.
