What is the Difference Between Lithium and Strontium Salts?

The main difference between lithium and strontium salts lies in the oxidation state of their cations and their colors in a flame test. Here are the key differences:

1. Oxidation State: Lithium salts have their cation in the +1 oxidation state, while strontium salts have their cation in the +2 oxidation state.
2. Flame Test: Both lithium and strontium salts emit a red color in a flame test, but strontium gives a much more intense and saturated crimson color than lithium. The colors are close, especially without a color chart for comparison.
3. Position in the Periodic Table: Lithium is a group 1 alkali metal, while strontium is an alkali earth metal in group 2 of the periodic table.
4. Solubility in Water: Some lithium salts, like lithium chromate, are exceptionally soluble in water, while strontium chromate is insoluble.
5. Uses: Strontium salts are used in various applications, such as strontium aluminate in glow-in-the-dark toys, strontium carbonate and most other strontium salts in firework production, and strontium chloride in toothpaste production. Lithium salts are primarily used in the manufacturing of rechargeable batteries for electronic equipment and non-rechargeable batteries.

Comparative Table: Lithium vs Strontium Salts

Here is a table comparing the differences between lithium and strontium salts:

The key difference between lithium and strontium salts is their cation's oxidation state. Lithium salts have a cation in the +1 oxidation state, while strontium salts have a cation in the +2 oxidation state. Both lithium and strontium are metals found in group 1 and group 2 of the periodic table, respectively.

In a flame test, lithium gives a less intense red color, while strontium produces a more intense red or reddish-orange color. However, the colors are very close, making it difficult to distinguish between them without a color chart for comparison. The solubility of both lithium and strontium salts in water varies depending on the specific salt. They are used in various applications, such as batteries, glass manufacturing, glow-in-the-dark toys, firework production, and toothpaste production.
