acids
Bases are capable of neutralizing __?
indicator
tells you if something is present
Polyprotic Acids
Donate 3 H+ or more
Base
Any of various water-soluble compounds capable of turning litmus blue and reacting with an acid to form a salt and water. Bitter tasting and slippery feel. Don't react with metals or carbonates.
properties of acid
conducts electricity, changes the color of (litmus) dye from blue to red, tastes sour, neutralizes properties of a base, expels hydrogen gas when in contact with metals
salt
the taste experience when salt is taken into the mouth
neutralization reactions
acidic and basic compounds react, neutralizing the other
amphoteric
water and other substances that can act as both acids and bases
conjugate base
what remains after proton is lost
buffer
maintains constant pH, made of weak acid and conjugate weak base(salt)
weak electrolyte
a solution that conducts electricity poorly because only a fraction of the solute exists as ions
what is a metabolic alkalosis?
HCO3- > 28
hydrogen
What is the element that acids combine with other non metal elements?
a compund which produces an excess of hydroxide ions in solution
base
Mechanical digestion
food is physically broken down into more manageable pieces, a physical change
end point
when the indicator changes to the appropriate color, not always neutral.
Ionic salts
what are insoluble in water however will dessolve to some extent?
a procedure in which a solution of known concentration undergoes a specific chemical reaction of known stoichiometry with a solution of unknown solution.
Titrations
What acid is produced in the stomach
Hydrochloric acid
S/sx of Hyper K?

Acidic solution
a solution whose pH is less than 7
Acid Rain
Rain containing acids that form in the atmosphere when industrial gas emissions (especially sulfur dioxide and nitrogen oxides) combine with water
What is the rate that Ca Chloride is given?
1gm/hr.
hydronium ion (H3O)
a water molecule that gains a hydrogen ion becoming positively charged
Bronsted-Lowry acid
molecule or ion that is a PROTON DONOR (all Arrhenius acids are Bronsted-Lowry acids)
name 2 acids??
and can they cause damage??
#1 sulfuric acid.
#2 nitric acid.
and yes it cuase damage in acid rain.
ADH is released in response to
FVD or high osmolarity and thirst.
The cause of HyperK is?
use of supplements, , movement of K due to hypoxia or acidosis, sepsis, trauma, crushing
