How many mL of 0.100 M NaOH are needed to neutralize 50.00 mL of a 0.150 M solution of CH3CO2H, a monoprotic acid? How many mL o

Rama09 [41]

Answer:

We need 75 mL of 0.1 M NaOH ( Option C)

Explanation:

Step 1: Data given

Molarity of NaOH solution = 0.100 M

volume of 0.150 M CH3COOH = 50.00 mL = 0.05 L

Step 2: The balanced equation

CH3COOH + NaOH → CH3COONa + H2O

Step 3: Calculate moles of CH3COOH

Moles CH3COOH = Molarity * volume

Moles CH3COOH = 0.150 M * 0.05 L

Moles CH3COOH = 0.0075 moles

Step 4: Calculate moles of NaOH

For 1 mol of CH3COOH we need 1 mol of NaOH

For 0.0075 mol CH3COOH we need 0.0075 mole of NaOH

Step 5: Calculate volume of NaOH

volume = moles / molarity

volume = 0.0075 moles / 0.100 M

Volume = 0.075 L = 75 mL

We need 75 mL of 0.1 M NaOH

Balance the equation in acidic conditions. phases are optional. equation: cu no_{3}^{-} -> cu^{2 } no cu no−3⟶cu2 no

d1i1m1o1n [39]

Cu + 2NO₃⁻ + 4H⁺ → Cu⁺² + 2NO₂ + 2H₂O this is the balanced chemical equation in acidic medium.

<h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

Now write the given equation

Cu + NO₃⁻ → Cu⁺² + NO₂

Here we can see that all atoms other than O and H are balanced.

In the given equation oxidation number of Cu changes from 0 to +2.

In the given equation oxidation number of N changes from 5 to 4.

Now multiply by 2 with NO₃⁻ and NO₂.

Cu + 2NO₃⁻ → Cu⁺² + 2NO₂

Now ad the water molecules in right hand side to balanced the O atoms.

Cu + 2NO₃⁻ → Cu⁺² + 2NO₂ + 2H₂O

Now add 4H⁺ on the left hand side to balance the H atoms.

Cu + 2NO₃⁻ + 4H⁺ → Cu⁺² + 2NO₂ + 2H₂O

Thus from the above conclusion we can say that Cu + 2NO₃⁻ + 4H⁺ → Cu⁺² + 2NO₂ + 2H₂O this is the balanced chemical equation in acidic medium.
