What is the name of the acid Hi?

The exact answer to the question "What is the name of the acid Hi?" is Hydroiodic acid.

Based on the provided reference, the acid with the chemical formula HI is named Hydroiodic acid. The video excerpt clearly states, "So we have hydroiodic. And then we write acid. And that's the name for hi hydro iotic acid this is dr b and thanks for watching."

Understanding the Name: Hydroiodic Acid

The naming of binary acids, which are acids composed of hydrogen and one other element (usually a nonmetal), follows a specific pattern.

• Hydro- prefix: Indicates the presence of hydrogen in a binary acid.
• -ic acid suffix: Indicates that the nonmetal element forms an acid with hydrogen.
• The root of the nonmetal element's name is used in the middle. In this case, the element is Iodine, so the root is "iod".

Combining these parts gives "hydro-iod-ic acid", or Hydroiodic acid.

Naming Conventions for Binary Acids

Here's a quick look at how other similar binary acids are named:

• HF: Hydrofluoric acid (Fluoro -> Fluor)
• HCl: Hydrochloric acid (Chloro -> Chlor)
• HBr: Hydrobromic acid (Bromo -> Brom)
• HI: Hydroiodic acid (Iodo -> Iod)

This pattern is consistent for Group 17 elements (halogens) when forming binary acids with hydrogen.

Chemical Formula and Name

Understanding this naming convention helps in identifying other binary acids based on their formula or naming them correctly when given the formula.
