Chapter 4, Problem 87a
A solution of 100.0 mL of 0.200 M KOH is mixed with a solution of 200.0 mL of 0.150 M NiSO4. (a) Write the balanced chemical equation for the reaction that occurs.
Verified step by step guidance1
Identify the reactants: KOH and NiSO_4.
Determine the products of the reaction: KOH is a strong base and NiSO_4 is a salt, so they will undergo a double displacement reaction to form Ni(OH)_2 and K_2SO_4.
Write the unbalanced chemical equation: KOH + NiSO_4 -> Ni(OH)_2 + K_2SO_4.
Balance the chemical equation by ensuring the same number of each type of atom on both sides of the equation.
The balanced chemical equation is: 2 KOH + NiSO_4 -> Ni(OH)_2 + K_2SO_4.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Acid-Base Reactions
Acid-base reactions involve the transfer of protons (H+) between reactants. In this case, KOH acts as a strong base, providing hydroxide ions (OH-) that can react with metal cations. Understanding the nature of acids and bases is crucial for predicting the products of the reaction.

Acid-Base Reaction
Stoichiometry
Stoichiometry is the calculation of reactants and products in chemical reactions based on balanced equations. It allows us to determine the proportions of KOH and NiSO4 that will react, which is essential for writing the balanced chemical equation and understanding the quantities involved.

Precipitation Reactions
Precipitation reactions occur when two soluble salts react to form an insoluble compound, or precipitate. In this scenario, the reaction between KOH and NiSO4 may produce nickel hydroxide (Ni(OH)2), which is insoluble in water. Recognizing the solubility rules helps in identifying the products of the reaction.

Textbook Question
A 4.36-g sample of an unknown alkali metal hydroxide is dissolved in 100.0 mL of water. An acid–base indicator is added, and the resulting solution is titrated with 2.50 M HCl(aq) solution. The indicator changes color, signaling that the equivalence point has been reached, after 17.0 mL of the hydrochloric acid solution has been added. (b) What is the identity of the alkali metal cation: Li+, Na+, K+, Rb+, or Cs+?
