What is meant by Oxide?
Oxides are abundant in nature and have various types with distinct characteristics. These are chemical compounds with one or more oxygen atoms attached to another element. It comes into being when an element reacts with oxygen.
Formula:
W = Second Weight – First Weight
E w = [w2 / (Second Weight – First Weight)] × atomic weight of oxygen
Different types of Oxides
Here few types of oxides with their characteristics are discussed.
| Oxides | Detail |
| Metal Oxides | Metal oxides can be basic, amphoteric, or acidic, depending on their chemical properties. Examples include calcium oxide (Ca O) and magnesium oxide (MgO). |
| Non-Metal Oxides | Non-metal oxides are generally acidic and tend to react with bases to form salts and water. Examples include sulfur trioxide (SO3), and nitrogen dioxide (NO2), carbon dioxide (CO2). |
| Peroxides | They are known for their ability to release oxygen when heated or decomposed. Hydrogen peroxide (H2O2) is a common example of a peroxide. |
| Hydroxides | Although not strictly oxides, hydroxides are compounds that contain the hydroxyl group (-OH) along with a metal or non-metal. Examples of hydroxides include sodium hydroxide (NaOH) and calcium hydroxide (Ca (OH)2). |
| Binary Oxides | Binary oxides consist of only two elements, one of which is oxygen. Examples of binary oxides include carbon monoxide (CO), which is a non-metal oxide iron oxide (Fe2O3), which is a metal oxide. |
Examples
Example 1:
When the Weight of metal oxide for the Second = 55 grams and the Weight of metal for the first = 15 grams then determine the equivalent weight of oxygen.
Solution
Step 1:
Write the given values
Weight of metal oxide for second = 55 grams
Weight of metal for first = 15 grams
Step 2:
Using formula:
W = Second Weight – First Weight
Ew= [w2 / (w2 - w1)] × atomic weight of oxygen
Step 3:
Weight of oxygen (W) = 55-15 = 40 grams
Equivalent weight (Ew) = (55 / 40) × 8
Equivalent weight (Ew) = 11
Example 2:
Evaluate the equivalent weight of oxygen. When the Weight of metal oxide for the Second = 32 grams and the Weight of metal for the first = 16 grams
Solution
Step 1:
Write the given values
Weight of metal oxide for second = 32 grams
Weight of metal for first = 16 grams
Step 2:
Using formula:
W = Second Weight – First Weight
Ew= [w2 / (w2 - w1)] × atomic weight of oxygen
Step 3:
Weight of oxygen (W) = 32-16 = 16
Equivalent weight (Ew) = (32/16) × 8
Equivalent weight (Ew) = 16
