Answer #1

answer : C) NaCl

explanation:

HCl react with NaOH forms salt . total acid and total base consumed . so only salt and water remains . that is called salt solution.

HC l +   NaOH -------------> NaCl + H2O

1M          1M                            0        0 -----------> initial

0             0                            1 M    1 M ------------> equivalence point

A titration is carried out between hydrochloric acid and sodium hydroxide. At the beginning of the experiment, 12.00 mL of 0.9881 M hydrochloric acid is placed in an Erlenmeyer flask with additional water and the indicator, phenolphthalein. What is the molarity of the sodium hydroxide solution if it takes 5.55 mL to neutralize the acid and reach the end point? In the flask below, draw the chemical substances (other than water) present at the end point of the titration.
