Hydroselenic acid in formula form is
H2SeO4?
Yes. H2SO4 is sulfuric acid.
H2SeO4 is selenic acid.
No, the formula for hydroselenic acid is not H2SeO4. The correct formula for hydroselenic acid is H2Se.
To understand how to derive the formula and name of hydroselenic acid, it's important to understand how to name binary acids. Binary acids are acids that consist of hydrogen attached to another nonmetallic element.
The prefix "hydro-" is used in the name to indicate that the acid contains hydrogen. The root of the element's name is used, followed by the suffix "-ic" to indicate that the nonmetallic element is in the "higher" oxidation state when combined with hydrogen.
In the case of hydroselenic acid, the nonmetallic element is selenium (Se). The root name for selenium is "selen-", and since it is in its higher oxidation state, we use the "-ic" suffix. Therefore, the formula for hydroselenic acid is H2Se.
In contrast, H2SeO4 is selenic acid, which is derived from selenium with an oxidation state of +6 and oxygen. The "O" in the formula denotes the oxygen atom.
So, to summarize, the correct formula for hydroselenic acid is H2Se, not H2SeO4.
