Thermochemistry

• Temperature Conversion

°C = K - 273    K = °C + 273

• Heat transfer

Q = mcΔT

• Hess's Law (Enthalpy)

• Entropy

• Gibbs Free Energy

Chemical Equilibrium

• Equilibrium Constant.
  
    for a general reaction equation: aA + bB cC + dD

Solutions

• Molarity, M

• Parts per million, ppm

• dilutions

M₁V₁= M₂V₂

• Solubility product constant, K_sp

  for a general reaction:
   
    A_bX_{y (s)} bA⁺_(aq) + yX^–_(aq)

K_sp = [A⁺]^b × [X^–]^y 

Acids and Bases

• K_a and K_b

  for a general reaction:  
  
  H_bX_{y (s)} bH⁺_(aq) + yX^–_(aq)

• K_w

  H₂O_(l) H⁺_(aq) + OH^-_(aq)

• pH

pH = - log [H⁺]

• pH and pOH

pH + pOH = 14

• Titration (for 1:1 Acid:Base ratio)

M_AV_A = M_BV_B
