Which statement is true about sodium chloride (NaCl)?
It is a salt because it decreases the concentration of metallic ions.
It is an acid because it is formed by the reaction of a salt and an acid.
It is a salt because it is formed by the reaction of an acid and a base.
It is an acid because it increases the concentration of nonmetallic ions.
Correct.
Well, let me sprinkle a little humor on this question! None of those statements are true about sodium chloride (NaCl). Sodium chloride is actually a salt, but not because it decreases the concentration of metallic ions. It is formed by the reaction of an acid and a base, not a salt and an acid. And sorry to burst your bubble, but it's definitely not an acid that increases the concentration of nonmetallic ions. So, the correct statement is: It is a salt because it is formed by the reaction of an acid and a base. Keep those chemistry jokes coming!
To determine which statement is true about sodium chloride (NaCl), we need to understand its properties and formation.
Sodium chloride, or NaCl, is a compound that is commonly known as table salt. It is formed through the reaction of an acid and a base. In this case, the acid is hydrochloric acid (HCl) and the base is sodium hydroxide (NaOH). The reaction between HCl and NaOH produces water (H2O) and NaCl.
Based on this information, the correct statement is:
"It is a salt because it is formed by the reaction of an acid and a base."
Therefore, the statement claiming that sodium chloride is an acid or that it decreases the concentration of metallic ions or increases the concentration of nonmetallic ions is not accurate.
