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.
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.
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.
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.
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.
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 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.
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.
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.
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

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%
percent of decrease
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
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.
