Does anyone want to attempt to explain to me in very simple terms how to tell what chemical is acid and what is base in such formula's as SO2 + CaO --> CaSO3 Or Al(OH)3 + OH- ---> Al(OH)4-
A titration is performed in which 50.0 mL of 0.0463 M acetic acid (Ka = 1.8 x10^- 5) is titrated with 0.1000 M NaOH. Calculate the pH at the beginning of the titration (Vb = 0).
The rate of substitution of alkyl chlorides and alkyl bromides can be increased by adding a catalytic amount of sodium iodide.
Determine the rate law and the numerical value for K based on the following data :
