Introduction: We are conducting this experiment to identify how temperature affects the solubility of salt. To add on‚ by making this experiment we could see how temperature affects the solubility of a substance‚ the maximum number of solute particles that can dissolve in solvent particles. Also‚ how by changing the temperature we could see how if the solubility of the solute would either increase or decrease. This experiment connects with information we learn in class because of how in class

sink if put in salt water? Purpose: I want to know why the egg floats in fresh water and not salt water. I want to know if the egg will float in salt water‚ Also this shows why materials float easier in saltwater and sink in freshwater. Research: Since the egg’s density is higher than the density of freshwater the egg will sink. Density is mass per unit volume‚ which means a measure of how much mater is in a certain volume. If you add enough salt the egg will float again. The salt makes the water

learned about how salt affects the freezing point of water. In my science project I wanted to see if salt affected the freezing point of water. I started by doing some experiments. My first experiment was whether tap water or salt water would freeze first. I first started by mixing up the salt water warming it for one minute and warming the tap for one minute also. My second experiment was what ice cube would melt fastest. I started by getting two bowls. Two ice cubes‚ and salt. I began by sprinkling

Experiment 7 Investigating Stoichiometry with Sodium Salts of Carbonic Acid Introduction: The student will perform the experiment in order to find the percent yield by using the theoretical value found using the balanced equation for sodium carbonate as well as sodium bicarbonate. The objective is to stabilize the substances by titrations and finding the percent yield when all the data is collected. The purpose of this procedure is so that the student will get better understanding of stoichiometry

Global woman is a chapter by Barbara Ehrenreich which gives a consider the challenges and obstacles present in the lives of women which pursue migrant work. Many women which live in poverty stricken countries are faced with the challenge of providing for their children financially without the assistance of a man. This is not to say that men within the country are so well off that their assistance would solve the problem‚ but when poverty is common within a nation‚ daily life can be challenging.

percentage by mass of water in Epson salt? DISCUSSION- When a crystal forms from water solutions‚ it takes a certain amount of water as part of the crystalline structures. The water is not covalently bonded to the host molecule or ion. Water is taken up in definite proportion in relation to the mass of the crystalline structure. This water that is trapped inside the hydrated solid structure is called water of crystallization or water of hydration. A salt with associated water of crystallization
