Chapter 2: Problem 87

Write the chemical formulas and names of binary acids and oxoacids that contain Group 7A elements. Do the same for elements in Groups \(3 \mathrm{~A}, 4 \mathrm{~A}, 5 \mathrm{~A},\) and \(6 \mathrm{~A}\).

Short Answer

Expert verified
Binary acids for group 7A are HF, HCl, HBr, HI. Oxoacids can vary like HClO2, HClO3, HClO4 etc. Group 3A, 4A, 5A and 6A binary acids are like H3BO3, H2CO3, H4SiO4, HNO3, H3PO4, H2SO4, H2SeO3, H2SeO4 among others.

Step by step solution

01

Define Acids

A binary acid consists of two elements, hydrogen and a second nonmetal. A binary acid is named by the prefix 'hydro-', the first syllable of the second element, and 'ic' as the ending followed by acid. An oxoacid, also known as oxyacid, contains hydrogen, oxygen, and another element. Oxoacids are named by changing the last two syllables of the anion to 'ic' and adding 'acid'.
02

Formulas for Group 7A Elements

The elements in group 7A are Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I) and Astatine (At). The binary acids can then be HF (Hydrofluoric Acid), HCl (Hydrochloric Acid), HBr (Hydrobromic Acid), HI (Hydroiodic Acid). The Oxoacids, since they have oxygen, tend to have various different formulas and names. Chlorine as an example can exist as HClO2 (Chlorous Acid), HClO3 (Chloric Acid), and HClO4 (Perchloric Acid).
03

Formulas for Group 3A, 4A, 5A, and 6A Elements

Group 3A elements like Boron can form oxoacids like H3BO3 (Boric Acid). Group 4A elements like Carbon form H2CO3 (Carbonic Acid) and Silicon forms H4SiO4 (Silicic Acid). For group 5A elements Nitrogen forms HNO3 (Nitric Acid) and Phosphorus forms H3PO4 (Phosphoric Acid). Group 6A elements Oxygen does not form oxoacids with hydrogen since it preferentially forms water. Sulphur forms H2SO4 (Sulphuric Acid) and Selenium forms H2SeO3, H2SeO4 (Selenous and Selenic Acid respectively).
04

Recap

Start by identifying which group the element belongs to. If the element is from group 7A, it can form a binary acid using Hydrogen. If the element is from group 3A, 4A, 5A, or 6A, it likely forms an oxacid with Hydrogen and Oxygen. To name the acid, use the appropriate naming rules.
