Answer the following question given this paragraph: Acids are ionic compounds that produce positively charged hydrogen ions (H + ) when dissolved in water. Acids taste sour and react with metals. Bases are ionic compounds that produce negatively charged hydroxide ions (OH - ) when dissolved in water. Bases taste bitter and do not react with metals. Examples of acids are vinegar and battery acid. The acid in vinegar is weak enough to safely eat on a salad. The acid in a car battery is strong enough to eat through skin. Examples of bases include those in antacid tablets and drain cleaner. Bases in antacid tablets are weak enough to take for an upset stomach. Bases in drain cleaner are strong enough to cause serious burns. Q: What is produced when a base is dissolved in water? Choices: - alkaline ions - synthesis ions - ingredient ions - hydroxide ions A:
hydroxide ions
