What was the PH for each dilute basee tested in NH4OH(aq)?
The pH of dilute NH4OH(aq) solutions varies depending on concentration. Generally, a 0.1 M solution of NH4OH has a pH around 10-11, while a 1 M solution has a pH closer to 11-12. Higher concentrations of NH4OH will result in higher pH values.
How do you do parallel dilution?
Parallel dilution is the dilution of a solution with equal quantity of the same solvent with which the solution is made. e.g., 1mL of 100µg/ml strength aqueous solution can be diluted to 2mL of 50µg/mL strength solution by adding 1mL Water.
How many atoms of hydrogen are in one molecule of ammonum hydroxide?
Ammonium hydroxide does not technically exist as molecules, but its formula unit is NH4OH, which has five atoms of hydrogen in each formula unit.
What is a dilution series?
A dilution series is a set of solutions where each subsequent solution is made by diluting the previous one with a solvent. This is commonly used in laboratory experiments to create a range of concentrations for testing or analysis.
What is sequential dilution?
In a sequential solution different volumes of a stock solution is added to varying volumes of solvent to create new solutions of specific concentration. Mostly use to create lower concentration of solutions.

How many N atoms in 2 moles of NH4OH?
There are 12 nitrogen (N) atoms in 2 moles of NH4OH because each molecule of NH4OH contains one nitrogen atom. Two moles of NH4OH is equal to 2 x 6.02 x 10^23 molecules, with each molecule contributing one nitrogen atom.
How isotope dilution is used to determine blood volumes in living animals?
Isotope dilution is used to determine blood volumes in living animals by predicting their isotope numbers. An example is the radioactive isotopes have a 1/2 life and that would mean it goes down by half each time.
How do you do parallel dilution?
Parallel dilution is the dilution of a solution with equal quantity of the same solvent with which the solution is made. e.g., 1mL of 100µg/ml strength aqueous solution can be diluted to 2mL of 50µg/mL strength solution by adding 1mL Water.
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.

About how many animals are tested on each day?
About 40,354 animals get tested on each day including dogs,cats,guineapigs,hamsters and rabbits. That's not including the 17,739 mice that are tested on.
How is geometric dilution similar to doubling?
Geometric dilution is similar to doubling in that both processes involve incremental increases based on a consistent ratio or factor. In geometric dilution, a solution is progressively diluted by adding an equal volume of solvent or diluent to each step, similar to doubling where each quantity is multiplied by two. Both methods aim to achieve a desired concentration or volume through a systematic approach. This structured scaling allows for precise control over the final outcome in both scenarios.
What does CPT code 87186 stand for?
Susceptibility studies, antimicrobial agent; microdilution or agar dilution, each multi-antimicrobial, per plate
What are the steps to perform minimum inhibitory concentration test?
hellos, I'm currently handling a project dealing in Minimum inhibitory concentration and minimum bactericidal concentration. Had to create the whole protocol from scratch. what's the Standard protocol used when dealing MIC test on bacterial like E.Coli and S.aureus?
Are the linear regression equations same for aliquot and serial dilutions?
No, the linear regression equations for aliquot and serial dilutions are not necessarily the same, as they represent different dilution processes. An aliquot dilution involves taking a specific volume from a concentrated solution and diluting it with a solvent, while a serial dilution involves sequentially diluting a solution in a stepwise manner. Each process may yield different concentration-response relationships, which can result in distinct linear regression equations based on the specific dilution factors and measurement data.
