Consider This Reaction: $KOH + HBr \rightarrow KBr + H_2O$.Which Statement Is Most Likely True About HBr?A. It Turns Blue Litmus Red.B. It Reacts With Carbon Dioxide To Form A Carbonate.C. It Feels Slippery.
Understanding the Reaction: KOH + HBr → KBr + H2O
The given reaction is a classic example of a neutralization reaction between a strong base (KOH) and a strong acid (HBr). In this reaction, the strong base (KOH) reacts with the strong acid (HBr) to form a salt (KBr) and water (H2O). This reaction is a type of acid-base reaction, where the acid (HBr) donates a proton (H+ ion) to the base (KOH), resulting in the formation of water and a salt.
Analyzing the Statements
Now, let's analyze the given statements to determine which one is most likely true about HBr.
A. It turns blue litmus red
Blue litmus is a pH indicator that turns red in acidic conditions. Since HBr is a strong acid, it will donate a proton (H+ ion) to the litmus, causing it to turn red. Therefore, statement A is true.
B. It reacts with carbon dioxide to form a carbonate
HBr is a strong acid and does not react with carbon dioxide to form a carbonate. Carbonates are typically formed by the reaction of a base with carbon dioxide. Since HBr is an acid, it will not react with carbon dioxide to form a carbonate. Therefore, statement B is false.
C. It feels slippery
HBr is a strong acid and does not have a slippery texture. The slippery texture is typically associated with bases, such as soap or other surfactants. Since HBr is an acid, it will not feel slippery. Therefore, statement C is false.
Conclusion
Based on the analysis of the statements, the most likely true statement about HBr is:
- A. It turns blue litmus red
This is because HBr is a strong acid that will donate a proton (H+ ion) to the litmus, causing it to turn red.
Understanding the Properties of HBr
HBr is a strong acid that is highly corrosive and toxic. It is a colorless gas at room temperature and has a characteristic pungent odor. HBr is highly soluble in water and is used in various industrial applications, such as the production of polyethylene and polypropylene.
Safety Precautions
When handling HBr, it is essential to exercise extreme caution due to its highly corrosive and toxic nature. HBr can cause severe burns and eye damage, and prolonged exposure can lead to respiratory problems. It is essential to wear protective gear, including gloves, goggles, and a face mask, when handling HBr.
Conclusion
In conclusion, the most likely true statement about HBr is that it turns blue litmus red. This is due to its strong acidic nature, which causes it to donate a proton (H+ ion) to the litmus, resulting in a color change. It is essential to exercise caution when handling HBr due to its highly corrosive and toxic nature.
