**Determining the pH of an Aqueous Solution of Ammonium Bromide** *The pH of an aqueous solution of **0.223 M ammonium bromide, NH4Br (aq)**, is [____].*This solution is [ ] ▼.---**Explanation:**To calculate the pH of an aqueous solution of ammonium bromide (NH4Br), we need to understand the acidic or basic nature of the solution.1. **Ammonium Bromide (NH4Br):** Ammonium bromide is a salt formed from the reaction of ammonia (a weak base) and hydrobromic acid (a strong acid).2. **Dissociation in Water:** NH4Br dissociates completely in water to form NH4+ (ammonium ion) and Br- (bromide ion).3. **Effect of Ions on pH:** - **NH4+ (Ammonium Ion):** Acts as a weak acid, capable of donating a proton (H+) to water to form NH3 (ammonia) and H3O+ (hydronium ion), increasing the acidity (lowering the pH) of the solution. - **Br- (Bromide Ion):** Since it is the conjugate base of a strong acid (HBr), it does not affect the pH significantly.To find the exact pH, the dissociation constant (Ka) for NH4+ and the concentration of NH4+ in the solution are considered. The pH can then be determined using appropriate calculations.**Nature of the Solution:**The drop-down box labeled "This solution is" likely contains the following options:1. Acidic2. Neutral3. BasicBecause NH4+ is a weak acid, an aqueous solution of ammonium bromide will be slightly acidic.**Conclusion:**Students can use this step-by-step approach to determine the pH of any solution and reason out whether it is acidic, neutral, or basic.

Sodium hydrogen carbonate NaHCO3, also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid HCl, which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HCl through this reaction: HCl(aq)+NaHCO3(aq)→NaCl(aq)+H2O(l)+CO2(g) The CO2 gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a woman suffering from indigestion can be considered to be 200.mL of a 0.089M HCl solution. What mass of NaHCO3 would she need to ingest to neutralize this much HCl? Be sure your answer has the correct number of significant digits.
