Serial Vs Parallel Dilution
SERIAL vs DIRECT. Time to apply new thinking to IC. 50 determination and dose-response analysis? The serial dilution method is standard practice in the preparation of dose- response series for IC. 50 determination. However, it is well recognised that inadequacies in the liquid handling or mixing technique will.
Parallel dilution is the dilution of a solution with equalquantity of the same solvent with which the solution is made. e.g.,1mL of 100µg/ml strength aqueous solution can be diluted to 2mL of50µg/mL strength solution by adding 1mL Water.

Definition of dilution and dilution factor?
As I understand it, the dilution refers to the dilution ratio. If you add 1 part of something to 4 parts of something else, the dilution ratio is 1 to 4. The dilution factor counts all the parts and expresses the same thing as 1 out of 5.

What is the opposite of dilution?
How much quinine in hyland's homeopathic leg cramps with quinine?
Realistically? None. Homeopathic medications are heavily diluted. The quinine dilution is a 3x (or approximately 1.5 c) dilution. So for the sake of easy math lets say it's an even 2c dilution. That means the quinine is diluted 1 part quinine in 100 parts dilution (like water) and part of that dilution is diluted in another 1:100 parts of dilution (more water). so...what's that work out to? One molecule of quinine per 10,000 molecules of…

Direct dilution vs double dilutions?
Direct dilution using the exact dose needed to get a specific response so that the dose is a stochastic variable, showing tolerance distribution. Double dilution is when the isotopic composition of two blends is the same.
How could concentration of ions decrease with dilution?
ion cocentration donot decrease with dilution. it is the density of ions that decreases with dilution. because earlier the amt of ions that were present in an unit volume has been moved farther through dilution so at that unit volume we get concentration of ions less than previously it was, but overall the concentration of ions remain constant.
Explain effect of dilution on the conductivity a strong and weak electrolyte?
as the dilution increases the no. of ion increases and they get free from there co-ions and can move independently from each other. so, by increasing dilution the rate of conductivity increases as more ions are available for conductance

How do you calculate dilution ratio?
A dilution ratio is a shorthand method to represent a dilution performed using integer ratios of solvent. For example let's say you have 100mL of an aqueous 1M solution. Transfer 25mL of this solution to a 100mL volumetric flask, and dilute with water to the 100mL mark. This solution is now 0.25M, a 1:4 dilution. I have seen this mistakenly reported as a 1:3 dilution, adding the two integers together to get the new solution…

What is serial dilution?
Serial dilution is usually 1/10 dilution. Therefore after a series of dilutions, you have a logarithmic curve of concentration (log10). Basically, if diluting 1/10 and starting off with 1 molar solution, first dilution = 0.1M, 2nd = 0.01M, 3rd = 0.001M. If making a 0.001M solution involved weighing out 0.005g of a salt for example, the error in making this solution out would be very large in comparison to weighing out 5g (1M) and diluting…

The percent ionization of a weak electrolyte upon dilution is increased. This is in accordance with Le Chatelier's principle. Dilution causes the reaction to shift in the direction of the larger number of particles to counter the effect of the decreasing concentration.

What is a Dilution Test?
To ensure the accuracy of your results, chemical analysis requires you to calibrate your instruments. Some techniques operate and are applicable to a wide range of concentrations of the species in question. Preparing a series of solutions to generate a calibration curve of instrument response is fairly labor intensive and provides many points where errors may occur.
TL;DR (Too Long; Didn't Read)
You can use serial dilutions of a solution of known concentration to calibrate lab equipment and ensure its accuracy.
Errors
Making multiple calibration standards for your lab equipment means measuring out a solution of known concentration and diluting it to make a series of lower concentrations. You must exercise care at each step; any errors will increase through multiple dilutions. Since the point is to calibrate your instruments, errors in this process will compromise your final results; in fact, you could have serious problems with your data.
Serial dilution only requires that you measure your solution of known concentration one time. Each calibration standard that follows comes from the previous one. The absolute size of the error in each standard becomes smaller and smaller as the concentration drops.
Easier and Faster Preparation of Calibration Standards
Each calibration standard solution is prepared based on the previous calibration standard. The process involves taking a portion of the previous standard and diluting it with the solvent to obtain the next calibration standard. The errors introduced with each successive dilution drops proportionately with the solution concentration. Preparing a series of calibration standards by this method reduces the amount of required time. Most calibration standards span a large range of concentrations, so the accuracy of the calibration standard prepared increases.
Calibrations Solutions More Evenly Spaced
The calibration standards should span the entire concentration range of the analysis. The more evenly spaced the calibration standards are over this range, makes the results of the analysis more reliable. Evenly spaced calibration standards are easier to prepare using serial dilution. Each successive standard uses a small portion of the previous standard, which is diluted by solvent to generate the next calibration standard in the series.
Greater Variability in Calibration Range
The dilution factor chosen for the series of calibration standards is achievable by using serial dilution. The progression of calibration standard concentration is always a geometric series. Consider the example of making the first standard at 1/3 the concentration of the known, the next calibrant would be 1/9th the concentration of the known and the following two calibrants formed are 1/27th and 1/81st. This becomes a much greater advantage when the span of the calibration standards must cover several orders of magnitude in concentration.
