· A 1.4350-gram of KHP (actual formula = KHC8H404; molar mass = 204.22 g/mol) was dissolved in 50.00 mL of deionized water. The
resulting solution was titrated with NaOH solution of unknown
concentration. If 32.85 mL of the NaOH solution was required to reach
the equivalent point, what was the molar concentration of the NaOH
solution? The acid-base reaction is as follows:
KHC8H404(aq) + NaOH(aq)
NakCgH404(aq) + H2O(1)

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the answer is c. nacl
