Solution 5.5

Students conducted an investigation to test the solubility of several substances. They placed ten grams of each substance into separate beakers. Next, they added 100 milliliters of warm water and stirred each mixture. Finally, they constructed the following chart based on their observations. Based on the data, which conclusion is valid/true?

• Salt and sugar are not soluble in water.

• All of the substances are soluble in water.

• Sand and pepper are not soluble in water.

• None of the above.
