What are the six solubility rules?

Solubility Rules

Alkali metal (Group IA) compounds are soluble.
Ammonium (NH4+) compounds are soluble.
Nitrates (NO3-), chlorates (ClO3-), and perchlorates (ClO4-) are soluble.
Most hydroxides (OH-) are insoluble.
Most chlorides (Cl-), bromides (Br-) or iodides (I-) are soluble.

How do you read a solubility table?

The Solubility Table has two columns. The left column indicates substances that dissolve in water, denoted as soluble substances or (aq). The right column indicates substances that won’t dissolve in water, denoted as insoluble substances or (s).

What is the general rule of thumb for determining the solubility of 2 substances?

Generally both solvents and solutes are separated into two types: polar/ionic and non-polar. The rule of thumb is that “like dissolves like”. Polar/ionic solvents dissolve polar/ionic solutes and non-polar solvents dissolve non-polar solutes.

What is the trend of solubility in Group 2?

Group II metal hydroxides become more soluble in water as you go down the column. This trend can be explained by the decrease in the lattice energy of the hydroxide salt and by the increase in the coordination number of the metal ion as you go down the column.

What are the rules in solubility?

Salts containing Group I elements (Li+,Na+,K+,Cs+,Rb+) are soluble .

Salts containing nitrate ion (NO 3-) are generally soluble.

Salts containing Cl -,Br -,or I – are generally soluble.

Most silver salts are insoluble.

Most sulfate salts are soluble.

Most hydroxide salts are only slightly soluble.

What do the solubility rules predict?

The solubility rules are a useful guideline to predict whether a compound will dissolve or form a precipitate . There are many other factors that can affect solubility, but these rules are a good first step to determine the outcome of aqueous solution reactions. The key to predicting a precipitate is to learn the solubility rules.

What is the solubility rule in chemistry?

Solubility rules dictate whether a compound will dissolve in water. Therefore, solubility rules can help you determine what state the products of a chemical reaction will have. When you write out a chemical equation, you can use solubility rules to label the predicted states of the compounds involved.
