Welcome to the article Determine if 100 grams of water can dissolve potassium nitrate at 313 K A True B False. On this page, you will learn the essential and logical steps to better understand the topic being discussed. We hope the information provided helps you gain valuable insights and is easy to follow. Let’s begin the discussion!
Answer :
Final answer:
The statement '100 grams of water dissolve potassium nitrate at 313 K' lacks the exact amount of potassium nitrate that can be dissolved. However, potassium nitrate is soluble in water and its solubility increases with temperature. At 313 K, around 60 grams of potassium nitrate can be dissolved in 100 grams of water.
Explanation:
The statement '100 grams of water dissolve potassium nitrate at 313 K' requires additional information about the quantity of potassium nitrate being dissolved to determine its validity. However, potassium nitrate is indeed highly soluble in water and its solubility does increase with temperature. At 313 K (or 40 °C), one can dissolve approximately 60 grams of potassium nitrate in 100 grams of water.
The solubility of a substance is defined as the maximum amount of that substance that can dissolve in a certain amount of solvent (e.g., water) at a certain temperature. In this case, the substance is potassium nitrate and the solvent is water. The temperature stated, 313 K, is the temperature at which the solubility is being measured.
Therefore, while the statement that 100 grams of water can dissolve potassium nitrate at 313 K is likely true, an exact amount of potassium nitrate that can be dissolved is missing in the statement, making it less informative.
