In a laboratory 0.500 moles of NAOH is completely dissolved in distilled water to form 400.0 mL of NAOH. The solution is then used to titrate a solution of HNO3.

Which answer choice correctly completes the equation by filling in the formulas of the products in this titration reaction?

NaOH(aq) + HNO3(aq) —> —————- + —————-


1: NaNO2(aq) + H2O2(L)

2: NaNO3(aq) + H2O(L)

3: HNaNO3(aq) + OH(L)

4:H2NO3(aq) + NaO(L)

Answer:

The answer to your question is number 2. NaNO₃ + H₂O

Step-by-step explanation:

The reaction that is represented in this problem is an acid-base reaction. An acid-base reaction is a double displacement reaction.

The cation of a reactant attaches to the anion of the other reactant and viceversa.

Reactants NaOH and HNO₃

Cations Na⁺ H⁺

Anions OH⁻ NO₃⁻

Following the previous rule

Products NaNO₃ + H₂O

The products are a salt and water.
