Acid Flashcards
Acetic Acid
HC2H3O2
Larger Ka
= stronger acid
Phosphoric Acid
H3PO4
Large Kb
Strong base

Beers Law of Absorbance
Depends on absorbivity of substance, concentration thickness
Electrical Power
P= I * V
Watt= amp * volt
Units of J/sec
Electrical Energy
Energy = power * time
J = J/s. * s
Unit: kWh
1 Volt = ?
1 Volt = 1 Joule / coulomb
Electric current =
Electric current = movement of e-s
Unit: Amps. (= 1coulomb / second
Charge / Time)
I = V / R
Current = voltage / Resistance
Unit: coulombs / sec
Ohm sign ⚗️
1 ⚗️= 1 volt / Amp
Conductance
G, unit: mho
G = 1/ R
Amp/ Volt
Flow
Flow = vol / time
Or
Flow = area * velocity
Calculate change in velocity for changing tube diameter
v2 = v1 * ( A1/ A2)
Joule
Watt * second
Keq of
aA + bB —> cC + dD
Keq = [C]^c * [D]^d / [A]^a * [B]^b
pH Formula
pH = - log[H+]
Henderson Hasselbach Equation
pH = pKa + log([A-]/[HA])
pKa = -log[Ka]
Carbonic Acid
H2CO3
Cellular respiration gives off CO2,
CO2 —>
CO2 —> blood, it mixes with H2O to form H2CO3
Breaks apart into H+ & HCO3- when goes to renal & GI
If H2CO3 goes to lungs:
—> H2O + CO2
Normal
pH
CO2
HCO3-
Normal
pH. 7.35-7.45
CO2. 35-45mmHg
HCO3- 20-28mM
Kidney pH Control System
If pH low, kidney Increases H+ secretion
Lungs compensate for pH by
Increase respiratory rate
Buffer H+ excretion in urine
Add HPO4- to H+ in ultrafiltrate in renal tubule
—> H2PO4
H+ from dissociation of H2CO3 where the HC03- reabsorbed
Charge on electron
Coulomb (C)
Velocity=
Velocity = Flow/ Area
(.5)^ #of half lifes
What’s left of some w 1/2 life
Anion Gap
Normal = 8-16
Na - (Cl - HCO3)
Use to determine cause of Met Acidosis
high w/ addition of acid:
ketoacidosis, DKA, lactic acidosis, CO/CN poisoning, renal failure, injest Acid
Normal: bicarbonate loss,
diuretics, diarrhea, renal tubular acidosis,
