to pure substance, where m is the total mass and V is the total volume. However, corresponding quantities may also be defined for a mixture as m/n and V/n, where n = ∑ i n. These quantities are called the mean molar mass and the mean i molar volume respectively.Chapter1-1 ...

The strength of weak acid depends on the degree of dissociation. The more the... Learn more about this topic: Weak Acids | Definition, List & Examples from Chapter 28/ Lesson 13 69K Learn the definition of weak acids, study common examples, discover the difference between strong and weak ...
Molarity is dependent on temperature because the volume of solution changes when heated or cooled. For example, assume we dissolve 0.5 moles of sodium chloride salt in 1 liter of water at 1 degree Celsius. This forms a solution with a salt concentration of 0.5 molar, which is similar to ...
This behavior is quantified by the acid dissociation constant (Ka). Therefore, strong acids exhibit a higher degree of ionization compared to weak acids at the same pH, which affects their reactivity and behavior in chemical reactions. Different ammonium salts—ammonium sulfate (AS), ammonium ...
