produces hydroxide ions in solution
acid and base
is an electrolyte
acid and base
can be detected with an indicator
base
soaps
acid and base
may be used to make fertilizer
acid
used in pickling
acid
produces hydronium ions
acid
Most compounds that produce this in aqueous solution are ionic
acid
exists in aqueous solution
acid
HCl is an example
base
Ammonia is a common example
acid and base
conducts electricity
acid
any substance that produces hydrogen ions. H+, in a water solution
base
Any substance that forms hydroxide ions, OH-, in a water solution
buffer
solution containing ions that react with added acids or bases and minimize their effects on pH
hydronium
H3O+ ions, which form when an acid dissolves in water and H+ ions interact with water
indicator
organic compound that changes color in acids or bases
neutralization
chemical reaction that occurs when the H30+ ions from an acid react with the OH- ions from a base t produce water molecules
pH
A measure of the concentration of hydronium ions in a solution using a scale ranging from 0 to 14, with 0 being the most acidic and 14 being the most-basic
salt
a compound formed when the negative ions from an acid combine with the positive ions from a base
soaps
organic salts with nonpolar, hydrocarbon ends that interact with oils and dirt and polar ends thats helps them dissolve in water
strong acid
any acid that dissociates almost completely in solution
strong base
any base that dissociates completely in solution
titration
process in which a solution of known concentration is used to determine the concentration of another solution
weak acid
any acid that only partly dissociates in solution
weak base
any base that does not dissociate completely in solution
acid
proton donor
Properties of Acids
Sour taste, corrosive liquids, turn litmus red
Hydrochloric
HCl-
Gastric juice in stomach, pickling steel
Phosphoric
H3PO4-
Detergents and fertilizers
Sulfuric
(Battery Acid)
H2SO4-
Batteries/ Fertilizer
What do all acids have in common?
They all start with Hydrogen (H)
Base
proton acceptor
Properties of Base
bitter taste, slippery, Crystalline solid in the undissolved state, corrosive, turns litmus blue
Calcium Hydroxide
Ca(OH)2
Magnesium Hydroxide
Mg(OH)2
laxative
Sodium Hydroxide
NaOH
soap-making, drain cleaner
Ammonia
NH3
Dissociation of Acids
When an acid dissolves in water, the negative areas of near by water molecules attract the positive hydrogen in the acid- Hydronium ions formed (H3O+)
Dissociation of Bases
When bases that contain -OH dissolve in water, the negative areas of near by water molecules attract the positive ion in the base- Hydroxide (-OH) ions produced
strong acids
HCl, HNO3, H2SO4
strong base
NaOH
weak acids
acetic and carbonic acid
weak base
Ammonia
concentration
The amount of an acid or base dissolved in water
pH scale
A measurement of the concentration of H+ ions in solution
The greater the H+ ion concentration the ___ pH.
lower
7.4
pH of blood
Acidosis
When blood pH drops below 7.4, the body enters _____.
alkalosis
When blood pH rises above 7.4, the body enters _____.
pH above 7
Basic
pH below 7
Acidic
Neutralization
A chemical reaction between an acid and a base
Neutralization
Acid + Base ---> Water + Salt
Salts
Composed of a metal and a nonmetal other than oxygen, or a metal and a polyatomic ion
Soaps an Detergents
organic salts
soaps and detergents
have a polar head and non polar tail
saponification
process of soap making
Detergents
Similar to soap but without soap scum
strength
how much it dissociates
concentration
how much it dissolves
Anthocyanin
Chemical indicator that is found in red cabbage juice
endpoint
Point where indicator changes color in titration
