Answer
are negatively charged.
Explanation
1. Identify properties of acidic dyes Acidic dyes are negatively charged (anionic).2. Determine staining target They stain positively charged (basic) structures, not negatively charged ones.3. Assess pH environment Acidic dyes do not require low pH; they work best in slightly basic environments where cellular components are positively charged.4. Check solubility Acidic dyes are water soluble, not lipid soluble.
