step 1 So here in this question, NAHSO4, NAHSO4, dissociates as sodium ion and HSO4 minus ion. Now this

Is an aqueous solution of NaHSO4 acidic, basic, or neutral?...

Key Concepts

Acid Dissociation Equilibrium (Ka)

The bisulfate ion (HSO??) in water undergoes an equilibrium reaction where it partially dissociates into H? and SO?²?. The equilibrium constant for this process, denoted as Ka, quantifies the acid strength in this dissociation. The expression for this equilibrium is Ka = [H?][SO?²?] / [HSO??]. This equilibrium analysis is crucial for understanding how much H? is produced in solution and thereby determining the pH.

pH Calculation Using Equilibrium Analysis

Calculating the pH of an acidic salt like NaHSO? involves first recognizing that the salt completely dissociates into Na? and HSO??. Then, setting up the equilibrium for the partial dissociation of HSO?? (HSO?? ? H? + SO?²?) and applying the acid dissociation constant (Ka) allows one to solve for the equilibrium concentration of H?. Finally, the pH is obtained by taking the negative logarithm of the hydrogen ion concentration, providing a quantitative measure of the solution's acidity.

Acidic Salt

An acidic salt is formed when a strong acid reacts with a weak base or when one proton of a diprotic acid dissociates completely while the other proton is only partially dissociated. In the context of NaHSO?, the sodium cation (Na?) is neutral and the bisulfate anion (HSO??) acts as an acid. When dissolved in water, HSO?? donates a proton (H?), making the overall solution acidic.

Salt Hydrolysis

Salt hydrolysis refers to the reaction that occurs when the ions of a salt interact with water. In the case of NaHSO?, the bisulfate ion (HSO??) reacts with water to form hydronium ions (or H?) and sulfate ions (SO?²?). This process is responsible for the generation of additional H? ions in the solution, thereby lowering the pH and giving the solution its acidic character.
