## Questions & Answers

**Q: What’s the difference between Alka-Seltzer effervescent tablets and ReliefChews?**
A: Both effervescent tablets and ReliefChews are portable and deliver fast multi-symptom relief. Effervescent tablets dissolve in water for fizzy, refreshing relief you can hear, see and feel. ReliefChews are delicious and chewy.

**Q: What temperature of water should I use to dissolve Alka-Seltzer tablets?**
A: The best temperature is room temperature. Cold water will slow down dissolution and warm water can make it foam excessively.

**Q: Is Alka-Seltzer the same as baking soda?**
A: Not exactly. Baking soda (sodium bicarbonate) does not contain anhydrous citric acid, the main active ingredient in Alka-Seltzer effervescent tablets that relieve heartburn and acid indigestion.

**Q: What makes Alka-Seltzer fizz?**
A: Alka-Seltzer contains citric acid and sodium bicarbonate (baking soda). When you drop the tablet in water, the acid and the baking soda react – this produces fizz.

**Q: What are the active ingredients in Alka-Seltzer ReliefChews?**
A: ReliefChews contain calcium carbonate (antacid). Heartburn+Gas Relief Chews contain calcium carbonate (antacid) and simethicone (antigas).
