In science class, students are conducting an experiment testing substances to determine if they are acids or bases. In one group, students dip a piece of red litmus paper into an orange solution. The litmus paper does not change colors. The students then dip a piece of blue litmus paper into the same orange solution. The litmus paper turns red. Based on these observations, what can the students infer about the orange solution?

25%

Explanation:

A way to estimate the ionic character of a bond between two atoms is using the formula:

(χ₁-χ₂) / χ₁ * 100%

Where χ₁ is the electronegativity of the more electronegative atom of the bond, while χ₂ is the other atom's electronegativity.

In the case of this problem χ₁ is the electronegativity of F and χ₂ is Chlorine's.

So the estimate is:

(4.0-3.0) /4.0 * 100% = 25%
