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.

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.
What does CPT code 87186 stand for?
Susceptibility studies, antimicrobial agent; microdilution or agar dilution, each multi-antimicrobial, per plate
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 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?
Phenol coefficient test in microbiology?
Phenol coefficient test is best known screening test in which potency of a disinfactant is compared with that of phenol. A series of a dilutions of phenol and the disinfactant being tested are prepared. A standard amount of Salmonella tyhpii and Staphylococcus aureus are added to each dilution; the dilutions are then placed in a 20 to 37oC water bath. At 5-minute intervas, samples are withdrawn from each dilution and used to inoculate a growth medium, which is incubated for two or more days and then examined the growth. If there is no growth in the growth medium, the dilution at that particular time of sampling killed the bacteria. The highest dilution that kills the bacteria after 1o min. expousre, but not at 5min. is used to calculate the phenol coefficient. This is done by dividing the resiprocal of the appropriate phenol dilution.
What is an implication of the resource dilution hypothesis?
The resource dilution hypothesis suggests that having more siblings can lead to decreased parental resources available to each child, potentially resulting in lower educational attainment or achievement. This hypothesis highlights the importance of family dynamics and resource allocation in shaping individual outcomes.
