What else can I help you with?
When 1 g of sodium chloride NaCl is placed in 100 g of water a solution results Once the solution is prepared water is now considered what part of the solution?
The water is considered the solvent in the solution, as it is the component that dissolves the sodium chloride (solute) to form the homogeneous mixture. In this case, the water serves as the medium in which the NaCl molecules are dispersed.
An aqueous solution of sodium chloride is best classified as a?
An aqueous solution of sodium chloride is classified as a salt solution. It is formed by dissolving sodium chloride (NaCl) in water, which results in the formation of sodium ions (Na+) and chloride ions (Cl-) in the solution.
Does sodium chloride form when sodium hydroxide reacts with water?
No Sodium hydroxide solution results -- not sodium chloride.
What do you get when aqueous solutions of sodium carbonate and zinc chloride are combined?
When aqueous solutions of sodium carbonate and zinc chloride are combined, a double displacement reaction occurs. This results in the formation of zinc carbonate, which is a white solid precipitate that settles out of the solution, and sodium chloride, which remains dissolved in the solution.
What happens when KCI dissolves in water?
When potassium chloride (KCl) dissolves in water, it dissociates into potassium ions (K+) and chloride ions (Cl-). This results in the formation of an electrolyte solution, which can conduct electricity due to the presence of free ions in the solution.
Is Calcium chloride in water is endothermic or exothermic?
The dissolution of calcium chloride in water is exothermic, meaning it releases heat. This reaction results in an increase in temperature of the solution.
What happens if you mix solutions of sodium chloride and lead chloride?
When solutions of sodium chloride and lead chloride are mixed, a precipitation reaction occurs. Lead chloride is less soluble than sodium chloride, so lead chloride precipitates out of the solution as a solid, while sodium chloride remains dissolved. This results in the formation of a white precipitate of lead chloride.
A precipitate is expected to form when an aqueous solution of sodium sulfate is added to an aqueous solution of what is it ironIII chloride potassium chloride magnesium chloride or barium chlori?
A precipitate is expected to form when an aqueous solution of sodium sulfate is added to an aqueous solution of barium chloride. This reaction results in the formation of insoluble barium sulfate, which appears as a white precipitate.
What happens to sodium chloride when it dissolves in water?
When sodium chloride dissolves in water, the sodium and chloride ions separate and become surrounded by water molecules. This process is called dissociation, and it results in the formation of a clear, salty solution.
Why is it important that fehlings solution be freshly prepared?
Fehling's solution contains copper sulfate and potassium tartrate which can oxidize and degrade over time, leading to inaccurate results. Freshly prepared Fehling's solution ensures the reagents are at their optimal concentrations for reliable testing of reducing sugars.
What will be the observations when Zinc nitrate solution is added to Barium chloride solution?
A white precipitate of barium nitrate will form, while zinc chloride remains in solution. This reaction results in the formation of a solid called a precipitate, which indicates a chemical reaction has occurred.
Why does copper chloride solution appear to fade in color when mixed with aluminum?
When copper chloride solution is mixed with aluminum, a redox reaction occurs where the aluminum reduces the copper ions to form copper metal. This results in a color change from blue-green (copper chloride solution) to colorless (copper metal precipitate), giving the appearance of fading in color due to the formation of a solid copper instead of a colored solution.
