If pH decreases by 1 pH number on the scale then how much has the concentration of hydrogen ions increased by?
If pH decreases by 1 unit on the pH scale, it means the concentration of hydrogen ions has increased by a factor of 10. For example, if the original pH was 7 and it decreases to 6, then the concentration of hydrogen ions has increased by 10 times.
If you have 0.05 ml of an undiluted culture at a concentration of 3.6x10 6 CFU ml You then add 4.95 ml sterile diluent What is the dilution factor and what is the final concentration of cells?
The dilution factor is 1:100, as you're adding 4.95 ml to the original 0.05 ml. The final concentration is calculated by multiplying the original concentration by the dilution factor, resulting in a final concentration of 3.6x10^4 CFU/ml.
What happens when you dilute a substance?
Concentration of acid will decreases on dilution. Concentration means amount of 1 substance per unit amount of another substance in which 1st substance is dissolved or mixed. So if u increase the solvent( 2nd substance) i.e., on dilution, then the ratio '1st substance per unit 2nd substance' decreases. Hence concentration decreases.
Which membrane protein is responsible for restoring the original concentration of Na plus and K plus?
The sodium-potassium pump, also known as the Na+/K+-ATPase, is responsible for restoring the original concentration of sodium and potassium ions across the cell membrane. This pump actively transports three sodium ions out of the cell in exchange for two potassium ions pumped into the cell, using ATP energy to maintain the concentration gradients.
How do you convert DNA with a concentration of 660.92 ng per uL to 5000 ng per uL and end up with a total volume of 25uL?
To convert DNA with a concentration of 660.92 ng/uL to 5000 ng/uL in a total volume of 25 uL, you can calculate the volume of the original DNA required to reach the desired concentration. First, determine the amount of DNA needed in the final concentration (5000 ng/uL * 25 uL = 125,000 ng). Then, divide this amount by the original concentration to find the volume required (125,000 ng / 660.92 ng/uL ≈ 189.14 uL). Therefore, you would mix the original DNA with an appropriate volume of diluent to reach the desired concentration and then adjust the total volume to 25 uL.
Why does the percent ionization of acetic acid increase as the concentration of the solution decreases?
As you increase the concentration of the solution, the concentration of H+ does not change. Meaning, the concentration ionized does not change. Just the original concentration increases. Since percent ionization = (concentration ionized)/(original concentration) , and the original concentration is increased, the percent ionization therefore decreases.
If pH decreases by 1 pH number on the scale then how much has the concentration of hydrogen ions increased by?
If pH decreases by 1 unit on the pH scale, it means the concentration of hydrogen ions has increased by a factor of 10. For example, if the original pH was 7 and it decreases to 6, then the concentration of hydrogen ions has increased by 10 times.
How can one calculate the original concentration from dilution?
To calculate the original concentration from dilution, use the formula: C1V1 C2V2. Where C1 is the original concentration, V1 is the original volume, C2 is the final concentration, and V2 is the final volume. Rearrange the formula to solve for C1: C1 (C2V2) / V1. This will give you the original concentration.
How can one calculate the original concentration from a given dilution factor?
To calculate the original concentration from a given dilution factor, you can use the formula: Original concentration Final concentration / Dilution factor. This formula helps determine the initial concentration of a solution before it was diluted.
What is the Relationship of solute concentration and solvent concentration?
These words are the two parts of dissolution. A solute is what is being dissolved, and a solvent is what dissolves it. The most universal solvent is water, which means that most solutes can be dissolved into it. A solute (e.g. sugar) is dissolved in a solvent (e.g. water) to make a solution - sugar solution
What is the percent of a quantity that increases or decreases from its original amount?

What is the percent increase if the original value of 50 decreases by 18?
Since the original value of 50 decreases to 18, it has a % decrease and not a percent increase. % decrease = [(50 - 18)/50] x 100% = 64%
The percent of change found when the original amount decreases is called the percent of?
percent of decrease
What happens to the momentum when mass is slowly decreasing but the velocity keeps constant?
Momentum = mass x velocity. Here velocity is constant. So momentum is directly proportional to the mass. Hence as mass decreases momentum too decreases proportionaly. If mass is reduced to half of its original then momentum also gets reduced to half of its original
What is a Dilution Test?
A dilution test is a procedure used to measure the concentration of a substance in a solution by systematically diluting the solution and observing the impact on the concentration. This test helps to determine the original concentration of the substance by comparing it with the concentration after dilution.
In which year did Concentration original series begin to run on NBC TV?
1958
