How many milliliters of 4.8 M NaOH are needed to exactly neutralize 29 milliliters of 2 M HCl?

V₁ = 12.1 mL

Explanation:

Given data:

Volume of NaOH required to neutralize = ?

Molarity of NaOH = 4.8 M

Volume of HCl = 20 mL

Molarity of HCl = ?

Solution:

Chemical equation:

HCl + NaOH    →   NaCl  + H₂O

In neutralization reaction the equal amount of  H⁺ from acid and OH⁻ from base react to form water and salt is also formed.

Formula:

M₁V₁ = M₂V₂

M₁ = molarity of NaOH

V₁ = Volume of NaOH

M₂ = molarity of HCl

V₂ = volume of HCl

Now we will put the values.

4.8 M × V₁ = 2 M × 29 mL

4.8 M × V₁ =58 M. mL

V₁ = 58 M. mL / 4.8 M

V₁ = 12.1 mL

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
