What is the name of this ion? [tex]$H_3 O^{+}$[/tex]
A. water positive
B. hydrate
C. trihydrogen oxide
D. hydronium
Answer (2)
The ion H 3 O + is formed when a water molecule accepts a proton. The correct name for this ion is h y d ro ni u m .
Explanation
Identifying the Problem The ion in question is H 3 O + . We need to identify its correct name from the given options: water positive, hydrate, trihydrogen oxide, and hydronium.
Understanding the Ion Formation The H 3 O + ion is formed when a water molecule ( H 2 O ) accepts a proton ( H + ). This ion is commonly known as the hydronium ion.
Determining the Correct Name Therefore, the correct name for the H 3 O + ion among the given options is hydronium.
Examples
In chemistry, understanding the hydronium ion is crucial for studying acids and bases. For example, when an acid dissolves in water, it increases the concentration of hydronium ions. Measuring the hydronium ion concentration helps determine the pH of a solution, which is vital in various applications, from environmental monitoring to industrial processes. The concept of hydronium ions also helps explain chemical reactions in aqueous solutions.
The ion H 3 O + is called hydronium. This ion is formed when water ( H 2 O ) accepts a proton ( H + ). Therefore, the correct answer from the given options is D. hydronium.
