Natalia began to draw a diagram to compare bases and acids.

Question

Two overlapping circles with the word bases above the left circle and acids above the right circle. There is an X in the left circle in the portion, which is not part of the overlap.

Which label should be written in the area marked X?

conducts electric current
produces OH– ions
tastes sour
reacts with carbonates

Answer 1

In the context of a Venn diagram comparing bases and acids, the area marked X in the left circle (which represents bases) should be labeled with "produces OH– ions." This characteristic is specific to bases, as they release hydroxide ions (OH–) in solution.

The other labels can be assigned as follows:

• "tastes sour" – This is typically associated with acids.
• "reacts with carbonates" – This is also a characteristic of acids.
• "conducts electric current" – This can apply to both acids and bases, but is not specific to one type.

Thus, the label "produces OH– ions" is the appropriate choice for area X.
