A spill on her hand. She quickly washes it off and notes the liquid conducts electricity and turns litmus blue. The liquid is best described as

• A. a strong base
• B. a weak base
• C. a strong acid
• D. a weak acid

Answer: (B)

A liquid that turns blue on litmus is basic, not acidic. Conducting electricity shows it forms ions in solution, which bases do when they dissociate in water. The key distinction between strong and weak bases is how completely they dissociate. The information given confirms it’s a base and an electrolyte, but it doesn’t show full dissociation. Therefore, the best match among the options is a weak base.
