Which of these is a unique property of bases? a feels slippery b contains a carbon c conducts electricity in solution d tastes sour

A. Feels slippery

Explanation:

Bases are the only types of compounds that have a slippery feel.

B is wrong. Most bases do not contain carbon, but organic compounds always do.

C is wrong. Aqueous solutions of bases conduct electricity, but so do aqueous solutions of salts.

D is wrong. Most bases have a bitter taste. Acids have a sour taste.

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.
