What is a mixture that is high in concentration and low in concentration?
A very strong Acid --- or Base-. A pH=7 reading means an equal concentration of H+ and OH-. A pH reading of say 1 shows a very high concentration of H+ with an exceedingly low concentration of OH-.
Is diffusion an active mechanism?
False
What determines the direction in a substance diffuses across a membrane?
The concentration gradient determines the direction in which a substance diffuses across a membrane. The concentration gradient is a measure of how the concentration of a substance changes from one place to another.
When particles are moved through a membrane from a region of low concentration to a region oh high concentration the process is called what?
active transport
What chemical substance does diabetes produce?
The consequence of diabetus is a high blood glucose concentration.
What does the hydronium ion concentration measure for a substance?
The hydronium ion concentration measures how acidic a substance is. A high hydronium ion concentration means the substance is acidic. A low hydronium ion concentration means the substance is basic. You may be more familiar thinking of it as the pH scale. At pH = 7 [H3O]+ = 10-7 and [OH]- = 10-7
What ions are in a high concentration in a base?
OH-
How does the concentration of H plus and OH- ions determine pH?
pH = - log([H+]) , pOH = - log([OH-] , pH + pOH = 14 [X] = concentration of X
What does high concentration mean?
High concentration means high density, or a large amount of a particular substance in a mixture or solution.
What determines the strength of an acid and a base in water?
The concentration of dissociable H+ ions is a measure of the acidity of the substance. The concentration of dissociable OH- ions is a measure of the basicity of the substance.
Is it true that An acidic solution has a very high concentration of OH ions?
No it is false -it has a high concentration of H+ ions
A high concentration gradient means that the concentration of a substance is?
It means one side have high concentration.Other side has lower.
What is The net movement of particles of a substance from a high concentration to a low concentration?
DIFFUSION DIFFUSION
What is a mixture that is high in concentration and low in concentration?
A very strong Acid --- or Base-. A pH=7 reading means an equal concentration of H+ and OH-. A pH reading of say 1 shows a very high concentration of H+ with an exceedingly low concentration of OH-.
How do you make alkaline?
The concentration of dissociable OH- ions is a measure of the basicity of the substance. Greater the concentration of hydroxyl ions, greater is it alkaline.
When a substance moves from an area of low concentration to an area of high concentration while using energy the processed is term is?
When a substance moves from an area of low concentration to an area of high concentration while using energy the process is called active transport.
What substance increases the number of OH?
A substance that increases the concentration of hydroxide ions in solution (OH-), is referred to as an Arrhenius base.
