Good summary of effects of pH, temperature and concentrations of sodium hypochlorite on bactericidal activity is in a Google books document.
Household bleach is ~5% sodium hypochlorite, 50,000 PPM available Cl, pH 13.
Bactericidal activity doubles for every 10 degree C increase
Bactericidal activity doubles for every 4x concentration increase
Typical pH killing effects (25PPM available Cl): pH 6=2.5 min, pH7=3.5 min, pH13=465 min
Household vinegar added at same volume as household bleach reduces pH to just above neutral.
