of evaluation test showed that nano oil displacement agent can greatly reduce the oil-water interfacial tension at the concentration of3‰ with a stable condition in the formation during 80 days;it can change the wettability of rock surface to strongly hydrophilic with strong anti-adsorption ability...
electrolyte. the equilibrium is present between the unionised molecules of a particular substance and the ion formed in the solution is known as ionic equilibrium . the ionic compounds are generally acids, bases and salts. therefore the ionic equilibrium is present in them when dissolved in water ...
This example problem demonstrates how to calculate boiling point elevation caused by adding salt to water. When salt is added to water, the sodium chloride separates into sodium ions and chloride ions. The premise of boiling point elevation is that the added particles raise the temperature needed ...
