Amphoteric/acidic/basic

Postby Elizabeth Harty 1A » Tue Dec 03, 2019 10:07 am

Based on problem 6A.17 from the homework, how do you determine if an oxide is acidic basic or amphoteric?

Usually you would use the periodic table for this. Metals form basic oxides while nonmetals form acidic oxides. metalloids tend to form amphoteric oxides

You need to check what is bonded to the oxygen. If it is a metal, then it is basic. If it is a nonmetal, it is acidic. The metalloids can form amphoteric oxides.

for oxides its:
acidic = nonmetal
basic = metal
amphoteric = metalloids or a mix of nonmetals and metals

How do you know what is a metalloid based off of just looking at the periodic table?

Metalloids are on the diagonal band that Dr. Lavelle was talking about in lecture. It includes B, Si, Ge, As, Sb, Te, and Po.
