I was told that when a base is dissolved in water, the ions form ion pairs so it is difficult to separate them completely; is this true? And if so, why wouldn't this apply to acids?

Ion association of dissolved bases refers to the process in which positively charged ions from a base are surrounded by negatively charged ions from water molecules, forming a complex ion. This process occurs when a base dissolves in water and is affected by factors such as concentration, temperature, and pH.
Ion association can impact the solubility, conductivity, and reactivity of dissolved bases. The formation of complex ions can alter the behavior of the base in solution, making it more or less reactive towards other substances.
Ion association plays a crucial role in acid-base reactions by influencing the strength of the base and its ability to donate hydroxide ions. The degree of ion association can also affect the equilibrium constant and the rate of the reaction.
Increasing the concentration of a dissolved base can lead to a higher degree of ion association, as there are more ions available to form complex ions. Temperature can also impact ion association by influencing the strength of the intermolecular forces between ions and water molecules.
Yes, ion association can be reversed by changing the conditions of the solution, such as adjusting the concentration, temperature, or pH. This can cause the complex ions to dissociate and return to their original form as individual ions.
