HCO3-

bicarbonate

HCO3- a substance that is a base/antiacid primarily made in the kidney... the body's buffer

Acidosis

excessive acidity of body fluids, pH below 7.35 "osis" = the process of

a hydrogen ion is negatively charged, this means that it has ______________ an electron.

hydrogen ions have lost an electron

why are some acids safe to consume and others toxic?

the amount of H+ ions in an acid is what determines weather it can be safely eaten or not

What is the formula for pH?

-log[H+]

the seven on the scale represents a ___________ pH. what is one example of this?

7 = neutral... perfectly pure water

how does the pH scale work?

the scale works by converting H+ ion concentrations to a number between 0-14

In moving from a pH of 4 to a pH of 2, the concentration of H+ ions would be _____________ greater.

100x (each number you move up on the scale is actually ten times the H+ concentration than the number before it)

What is the normal range for the partial pressure of carbon dioxide?

35-45

What is the normal pH of blood?

74

Who developed the pH scale?

Soren P. Sorenson

alkalosis

The buildup of excess base (lack of acids) in the body fluids. "osis" = the process of

neutralization reaction

a reaction in which an acid and a base react in an aqueous solution to produce a salt and water

What is an amphoteric substance? example?

a substance that can act as both an acid and a base amino acids are amphoteric,

If your pH is less than 7.35, you are in a state of ____________________ .

acedemia

if a substance is acidic, it's number will always be below _______ on the scale.

acidic substances will always be below a 7. the further down on the scale, the more H+ ions a substance has.

what is the main difference between acids and bases?

acids produce H+ ions while bases accept them. (bases also produce OH- ions)

If your pH is greater than 7.45, you are in a state of ____________________ .

alkalemia

all acids produce _________ when dissolved in ___________.

all acids produce H+ ions when dissolved in water
