Reading the above graph to the nearest tenth of a milliliter, what is the volume of sodium hydroxide at the equivalence point?

Vlada [557]

Answer:

The volume of sodium hydroxide at the equivalence point is:

<u>14.9 mL of sodium hydroxide</u>.

Explanation:

<u>The equivalence point occurs when, in this case, the HCl is completely neutralized with the solution of NaOH, how you can see this doesn't occur in the last point but occurs in the nineteenth point, where the pH is no more acid (below to 7) but is 11 approximately</u>, then you must see in the X-axis from this point and you can see the volume is almost 15, by this reason I calculate the valor of 14.9 milliliters.
