  • Quantifying soapiness; theres pH, pKa and pO2, is there a p_soap or p . . .
    Soapiness or anything like that cannot be represented by a single number Hence no point in inventing such a quantity Just like we cannot associate a plain number to odors, soapiness is scientifically meaningless because it will be an umbrella term Just like the term polarity is misused, soapiness could be even worse
  • Why does soapy dishwater lose soapiness over time?

    I have a small question concerning the stirring bars cleaning I use mine in BOD test wastewater for 5 days and I want to clean them so my question is can I soak them overnight with sodium hypochlo
  • organic chemistry - Is it possible to prevent saponification by . . .
    doesn't really make any sense Free fatty acid salts are soaps Esters of free fatty acids are fats not soaps Changing the metal counter ions only makes a marginal difference to their soapiness Different fatty acids make different soaps Some non fatty acid compounds make good surfactants The fats that fatty acids are derived from are not soaps
  • Is there such a thing as a minimal soap molecule?
    It boils down to the definition of soap Wikipedia defines a soap as the salt of a fatty acid IUPAC claims the smallest fatty acid can be considered to have 4 carbons
  • Diluting two solutions together - Chemistry Stack Exchange
    The problem is that to get 2% (v v) of B from a 4 % (v v) solution of B then to make 1 litre of the final solution we would need 500 ml (0 5 L) of the 4 % stock solution of B (at 4 %)
  • everyday chemistry - Are acids effective in removing soap scum . . .

  • Newest soap Questions - Chemistry Stack Exchange
    Quantifying soapiness; there's pH, pKa and pO2, is there a p_soap or p_surfactance? Yes, $\mathrm{pH}$ is a concentration, $\mathrm{p}K_\mathrm{a}$ is a dissociation constant, and $\mathrm{pO_2}$ is a partial pressure
  • Why does bleach feel slippery? - Chemistry Stack Exchange
    Maybe it needs to be clarified that the salt of a strong base and a weak acid can conduct saponification Therefore the fact that bleach reacts with fatty acids creating soap, does not necessarily mean that bleach should be all just base (nor that something else other than saponification should be happe
