Yes, the concentration changes after dilution. By definition dilution means to lower the concentration.
dillution
Yes, the rate constant can change with concentration in a chemical reaction.
The concentration of the salt solution does NOT change- it is saturated.
Concentration per unit time, also known as rate of change of concentration, is a measure of how quickly the concentration of a substance is changing with respect to time. It indicates the speed at which a substance is being produced or consumed in a reaction or process. This can be calculated by dividing the change in concentration by the time interval over which the change occurred.
To increase the concentration of a solution, you can decrease the amount of solvent by boiling off, or by evaporation, or you can simply add more solute. Conversely, to decrease the concentration, you can add more solvent.
Sometimes this is possible.
The question is not clear; the concentration of salt in water can be very variable.
The change in hydrogen ion concentration is a 1000-fold increase when the pH decreases by 3 units. This is because the pH scale is logarithmic, with each unit change representing a 10-fold change in hydrogen ion concentration.
pH 2 -> pH 1
Yes, the concentration of a gas can change due to factors such as temperature, pressure, and volume. These changes can affect the number of gas molecules in a given volume, thus altering the concentration of the gas.
A change in pH of one unit represents a tenfold change in hydrogen ion concentration. For example, a solution with a pH of 4 has 10 times higher hydrogen ion concentration than a solution with a pH of 5.
B. Equilibrium - when equal particles continue to move in both directions there is no further net change in the concentration on either side
