Electrolytes
substance which dissolves in water to produce conducting solutions (cation+anion) (breaks into ions) TERM 2
weak electrolytes: defn
DEFINITION 2 compounds that dissociate to a small extent into ions when dissolved in water (usually have a double arrow) TERM 3
Strong electrolytes:
list
DEFINITION 3 HCl, HBr, HI, HClO4, HNO3, H2SO4, KBr, KI, NaCl, NaOH, KOH,.. (all ionic compounds) TERM 4
weak electrolytes:
list
DEFINITION 4 CH3CO2H, HF, HC2H3O2 (Acetic acid) TERM 5
non electrolytes:
list
DEFINITION 5 H2O, CH3OH (menthyl alcohol), C2H5OH (ethyl alcohol), C12H22O11 (sucrose), and most carbon compounds (molecular compounds
acid
compound that can donate H+. You can recognize acid formulas as those that start with H or end with COOH. ( i.e HNO3 and HCOOH) TERM 7
base
DEFINITION 7 is a compound that can accept H+. Base formulas often contain a metal cation with the hydroxide anion, OH-. Bases that do not contain OH usually contain N. (i.e NaOH and NH3) TERM 8
salt
DEFINITION 8 an ionic compound that is neither an acid nor a base. To identify a salt, look for a formula that contains a cation that is not H+ and an anion that is not OH-. (i.e NaBr and KCl) TERM 9
anion
DEFINITION 9 gains e- which makes it negative in charge (anion is written as SO24, the "2" indicating that it has two more electrons than it has protons) TERM 10
cation
DEFINITION 10 loses e- ( i.e. Na+)
reduction
gain of one or more electrons TERM 17
reducing agent
DEFINITION 17 causes reduction, loses on or more electrons , undergoes oxidation, oxidation number of atom INCREASES TERM 18
oxidizing agent
DEFINITION 18 causes oxidation, gains one ore more electrons, undergoes reduction, oxidation number of atom DECREASES TERM 19
de broglie wavelength
DEFINITION 19 wavelength = h/mv = h/mc=c/v=hc/E TERM 20
blamer series
DEFINITION 20 2nd shell; if excited e- drops to second shell then light emitted will be in the Balmer series
Principal quantum number
(n)
"n", describes the size and E level of the orbital (shell), eqn "2n^2" as n increases the distance from the nucleus increases and the E of the electrons increases TERM 22
angular momentum quantum number aka
spherical orbital (l)
DEFINITION 22 "l" , the subshell, ranges from 0 to (n-1), number of nodes TERM 23
subshell notation (l)
DEFINITION 23 l=0=s , 1=p, 2=d, 3=f TERM 24
magnetic quantum number
(m_l)
DEFINITION 24 "m_l" , (2l+1) ranges from -l to +l TERM 25
spin quantum number
(m_s)
DEFINITION 25 +1/2 or -1/
