Influence of Electrolytes
The influence of electrolytes on the solubility of gases is sometimes given by Sechenov (often spelled Setchenov) equation which accounts for the "salting out" (i.e., decreasing the solubility) or "salting in" (i.e., increasing the solubility) effect (see the article on activity coefficient). The Sechenov equation can be written as:
where:
- *z1 is the solubility of gas 1 in pure solvent
- z1 is the solubility of gas 1 in an electrolyte solution
- y expresses the salt composition

“I am always glad to think that my education was, for the most part, informal, and had not the slightest reference to a future business career. It left me free and untrammeled to approach my business problems without the limiting influence of specific training.”
—Alice Foote MacDougall (1867–1945)
“Important as fathers are, their influence on children shouldn’t be exaggerated just because they were ignored so long. There is no evidence that there is something especially good about fathers as caretakers. There are no areas where it can be said that fathers must do certain things in order to achieve certain outcomes in children. The same goes for mothers.”
—Michael Lamb (late–20th century)
