Difference in 1pH unit indicates how much fold change of H plus ion concentration?
10 times.
What is the concept of concentration?
The amount of a substance per defined space. Concentration usually is expressed in terms of mass per unit volume.
What is rate of reaction measured in?
Change in concentration of a substrate per second. This is the unit: (ΔMoles/dm^3) / s
How in terms of collision theory how a decrease in concentration can change the rate of a precipitation reaction?
Decrease in conc. means decrease in no. of molecules per unit volume. Since, molecules or atoms will less in number, the no. of colliding particles will be less. This will lead to decreased precipitation
What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
What does a change in pH of one unit represent in terms of hydrogen ion concentration?
-1 pH unit = *10 concentration

What kind of changes do you believe could make a difference in our unit?
change in Unit
Is a single unit change on the pH scale equivalent to 1 percent change in hydrogen ion concentration?

What shows a tenfold increase in concentration of H plus ions?
A change in pH of 1 unit is equivalent to a 10 fold change in the concentration of H+ ions. So, a 10 fold increase in H+ ions will lower the pH by 1 pH unit.
Which concentration unit is independent of temp?
The unit of concentration is Molar = Moles/Litre.
What is the difference between and accleration?
Acceleration is a change of velocity (per time unit).Acceleration is a change of velocity (per time unit).Acceleration is a change of velocity (per time unit).Acceleration is a change of velocity (per time unit).
What is defined as the amount of substance per unit of volume?
The amount of substance per unit of volume is defined as concentration in terms of chemistry. The amount of substance refers to the quantity over the volume.
What is the difference between volicity and accleration?
Acceleration is a change of velocity (per time unit).Acceleration is a change of velocity (per time unit).Acceleration is a change of velocity (per time unit).Acceleration is a change of velocity (per time unit).
What is rate of reaction measured in?
Change in concentration of a substrate per second. This is the unit: (ΔMoles/dm^3) / s
What is the concentration unit?
M. M stands for Molar, which is in moles/Liter. That's the unit of concentration.
