Can the concentration of the substance change if it is a gas?
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.
What is a change in concentration of a reactant or product over time?
The change in concentration of a reactant or product over time is known as the reaction rate. It is a measure of how quickly reactants are consumed or products are formed during a chemical reaction. This rate is typically expressed as the change in concentration per unit time.
Does ksp change with concentration?
No, the solubility product constant (Ksp) does not change with concentration. It is a constant value that represents the equilibrium between an ionic solid and its ions in a saturated solution at a given temperature.
How does the concentration of a pure liquid change throughout the course of a reaction?
The concentration of a pure liquid does not change throughout the course of a reaction since it is not involved in the reaction itself. The concentration of a pure liquid remains constant because its molecules do not participate in the reaction.
Does altering the permeability of the membrane change the equilibrium concentration of the solute in the cell?
Yes, altering the permeability of the membrane can change the equilibrium concentration of the solute in the cell. By adjusting how easily the solute can pass through the membrane, you can affect the balance between the concentration of the solute inside and outside of the cell, ultimately impacting the equilibrium concentration.
Does the rate constant change with concentration in a chemical reaction?
Yes, the rate constant can change with concentration in a chemical reaction.
Is the concentration change after dillution?
Yes, the concentration changes after dilution. By definition dilution means to lower the concentration.
How does concentration change after every spoon full of salt is added after the solution is saturated?
The concentration of the salt solution does NOT change- it is saturated.
What is concentration per unit time?
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.
Does a change in the concentration of reactants result a change in temperature?
Sometimes this is possible.
Why is there no change in the concentration of the NaCl solution?
The question is not clear; the concentration of salt in water can be very variable.
What is the change in hydrogen ion concentration when the pH decreases by 3 units?
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.
Which change shows a tenfold increase in concentration h ions?
pH 2 -> pH 1
Can the concentration of the substance change if it is a gas?
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.
What does a change in pH of one unit represent in terms of hydrogen ion concentration?
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.
Which term refers to the condition that exist when no net change in concentration results from diffusion A. concentration B. equilibrium C. osmosis D. Randomness?
B. Equilibrium - when equal particles continue to move in both directions there is no further net change in the concentration on either side
How do you calculate the initial rate of a reaction?
The initial rate of a reaction is calculated by measuring the change in concentration of reactants over time at the beginning of the reaction. This is done by dividing the change in concentration by the change in time. The initial rate is typically expressed in units of concentration per unit time.
