chem question

[ron p]

i was under the impression that a gal of water could hold only a certian amount of chem.
I see that someone has now started to advertise that they have a strpper that is stronger then HD80. I personnaly think the cost of the stronger stuff will make it cost prohibitive but on some jobs it may be worth it.

Under certain conditions you can get a 'super saturated' solution.

Usually this involves heating the solvent so that more solute will dissolve in it. As well the addition of surfactants which make water 'wetter' will allow for higher concentrations.

Most every mix uses pure water as the major component. However, no water from any economical source will be pure so extra solute needs to be added to counteract the effect of the impurities.

Higher concentrations are entirely possible where you have up to 100% of the solute and no water. This are frequently known as soap kits and reduce the costs of storage and handling because you add your own water to the dry chemicals.

Every chemical reacts with water in differing amounts. The amount and type of salts used, the strength of the chemical bonds, temperature of the solvent as well as atmospheric conditions (temperature, pressure and humidity).

Hope this helps? Cheers.

Michael is right about the kits.To compare, check the percentage after the kit has been mixed with water to make an accurate assessment of percentages. This way you will be comparing say 500 Lbs. to 500 Lbs. and not, to say 50 or 100 Lbs. Just an example.
