Quick Answer

The balanced chemical equation for the reaction of potassium hydrogen phthalate (KHP) with sodium hydroxide (NaOH) is:

\[\text { KHC} _ 8\text { H} _ 4\text { O} _ 4 ( aq) + \text { NaOH} ( aq) \rightarrow \text { KNaC} _ 8\text { H} _ 4\text { O} _ 4 ( aq) + \text { H} _ 2\text { O} ( l) \]

Step-by-step Solution

1. Identify the reactants and products: 
KHP: Potassium hydrogen phthalate (\(\text { KHC} _ 8\text { H} _ 4\text { O} _ 4\)
NaOH: Sodium hydroxide 
Products: Potassium sodium phthalate (\(\text { KNaC} _ 8\text { H} _ 4\text { O} _ 4\)) and water (\(\text { H} _ 2\text { O} \))

2. Write the unbalanced equation: 
\[\text { KHC} _ 8\text { H} _ 4\text { O} _ 4 + \text { NaOH} \rightarrow \text { KNaC} _ 8\text { H} _ 4\text { O} _ 4 + \text { H} _ 2\text { O} \]

3. Ensure the equation is balanced: 
Count the number of atoms of each element on both sides of the equation. 
Potassium (K), hydrogen (H), carbon (C), oxygen (O), and sodium (Na) atoms are all balanced.

4. Therefore, the balanced chemical equation is: 
\[\text { KHC} _ 8\text { H} _ 4\text { O} _ 4 ( aq) + \text { NaOH} ( aq) \rightarrow \text { KNaC} _ 8\text { H} _ 4\text { O} _ 4 ( aq) + \text { H} _ 2\text { O} ( l) \]

 

Supplemental Knowledge:

Balance is of utmost importance in chemistry; accurately representing mass conservation through chemical equations is vital. Potassium hydrogen phthalate (\(KHP\)) can be used in titration experiments to accurately represent base concentration such as sodium hydroxide. As KHP is monoprotic acid it donates one proton (\(H^ { + } \)) per molecule when reacting with bases like \(NaOH\) in acid-base reactions.

The reaction between \(KHP\) and \(NaOH\) is a neutralization reaction where an acid reacts with a base to produce water and a salt. The chemical formula for KHP is \(KHC_ 8H_ 4O_ 4\), and for \(NaOH\), it’s \(NaOH\).

 

Theory in Practice:

Balancing chemical equations is essential in various fields like pharmaceuticals, environmental science and industrial chemistry. Accurately determining concentration levels through titration ensures effective formulation or treatment of wastewater for medications or wastewater treatments.
