If the hydroxide concentration of a CH3COOH/CH3COO- buffer system is 0.000045 M, what is the acetate concentration if the acetic acid concentration is 0.74 and the dissociation constant, Ka, of CH3COOH is 6 x 10-9 ? A hot piece of metal at 450K is placed in pure water that has a volume of 55.0 mL which has an initial temperature of 25.3°C. After five minutes, equilibrium is established and a final temperature of 44.4°C is reached . What is the...
