1. Hydrochloric Acid with universal indicator
2. Sodium hydroxide with phenolphthalein indicator
3. Ethanol with universal indicator
4. Copper sulfate solution with no indicator Those who look after they leap know they're safe, because they're there to look. Those who look before they leap know they are still a cliff away from safety.
