Consider this reaction: $KOH + HBr \rightarrow KBr + H _2 O$
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.
Answer (2)
HBr is a strong acid.
Acids turn blue litmus paper red.
Acids do not react with carbon dioxide to form carbonates.
Acids do not feel slippery.
Therefore, the most likely true statement about HBr is that it turns blue litmus red. I tt u r n s b l u e l i t m u sre d .
Explanation
Analyzing the Problem We are given the reaction K O H + H B r → K B r + H 2 O and asked to determine which statement is most likely true about HBr. Let's analyze the properties of HBr to determine the correct statement.
Identifying HBr as an Acid HBr is hydrobromic acid, which is a strong acid. Acids have specific properties that we can use to evaluate the given statements.
Considering Litmus Paper Test Acids turn blue litmus paper red. This is a fundamental property of acids.
Considering Reaction with Carbon Dioxide Acids do not typically react with carbon dioxide to form carbonates. Carbonates are usually formed by the reaction of carbon dioxide with bases.
Considering Slippery Feel Acids do not feel slippery. Slippery feel is a characteristic of bases.
Concluding the Answer Based on the properties of acids, the most likely true statement about HBr is that it turns blue litmus red.
Examples
Acids and bases are fundamental concepts in chemistry with numerous real-world applications. For example, understanding the properties of acids like HBr is crucial in industrial processes such as metal etching and chemical synthesis. In the human body, hydrochloric acid (HCl) in the stomach aids in digestion. Knowing how acids react with different substances helps us to design safer and more efficient chemical processes and understand biological functions.
HBr is a strong acid that turns blue litmus paper red, does not react with carbon dioxide to form carbonates, and doesn't have a slippery feel. Thus, the most likely true statement about HBr is that it turns blue litmus red. The chosen option is A.
