What happens when CaBr2 is dissolved in water?

Back

When CaBr2 dissolves, it dissociates into three particles: one calcium ion (Ca^2+) and two bromide ions (Br^-), resulting in a total of 3 particles in solution.

Front

What factors affect solvation?

Back

Factors affecting solvation include agitation/stirring, temperature, and surface area. Adding dye does not affect solvation.

Front

How many milliliters of a 4M NaCl solution are needed to make 1 liter of a 0.4M NaCl solution?

Back

100 mL of a 4M NaCl solution is required to make 1 liter of a 0.4M NaCl solution.

Front

What is the effect of temperature on solubility?

Back

Generally, increasing temperature increases the solubility of solids in liquids, while the solubility of gases decreases with increasing temperature.

Front

What is a solubility curve?

Back

A solubility curve is a graph that shows the relationship between the solubility of a substance and temperature, indicating how much solute can dissolve in a solvent at various temperatures.

Which compound is most effective for melting ice on roads?

Back

Compounds like NaI, MgO, and KBr are all effective in melting ice on roads when the air temperature is below zero.
