What else can I help you with?
Is NaCl plus H2O a mixture?
Yes. When NaCl is added to water, it forms a solution, which is a homogeneous mixture.
What would be observed when NaCl is added to water?
When NaCl is added to water, the NaCl crystals dissolve and dissociate into Na+ and Cl- ions. This creates an electrolyte solution where the ions are free to move around in the water. The solution may also experience a temperature change due to the dissolution process.
What mass of water must be added to 255.0g NaCl to make a 15.00 percent by mass aqueous solution?
To make a 15.00% by mass aqueous solution with NaCl, the mass of NaCl is 255.0g. This means that 15.00g of NaCl is present in every 100.00g of solution. To find the mass of water needed, first calculate the mass of NaCl in the final solution, then subtract this amount from the total mass of the solution (water + NaCl).
What occurs when NaCl is added to water?
The boiling point of the solution increases, and the freezing point of the solution decreases.
What volume of water should be added to 23.4 g of NaCl to make 100.0 mL of 4.00 M solution?
To prepare a 4.00 M NaCl solution, first calculate the moles of NaCl in 23.4 g. Then, determine the volume of water needed to make a total volume of 100.0 mL minus the volume of NaCl solution. Add the water to the NaCl to make a 100.0 mL solution.
What is the solvent in NaCl?
Sodium chloride is a solute when is dissolved in water (the solvent).
When each what is added to water is the resulting solution acidic basic or neutral?
When each of the following is added to water, is the resulting solution acidic, basic, or neutral? a) HClO, b) NaCl, c) HCN, d) MgO, e) CH3OH
What is the chemical composition of a solution made by dissolving PH NaCl in water?
The chemical composition of a solution made by dissolving NaCl in water is sodium chloride (NaCl) and water (H2O).
What happens to NaCl in water?
NaCl is added to water when a saline water solution is necessary; NaCl is dissociated in water: NaCl -------------------Na+ + Cl-
What is the mole fraction of 18 mol NaCl in a solution of 100 mol water?
The mole fraction of NaCl in the solution is calculated by dividing the moles of NaCl by the total moles of NaCl and water. In this case, the mole fraction of 18 mol NaCl in a solution of 100 mol water is 0.15 (18 mol NaCl / (18 mol NaCl + 100 mol water)).
NaCl solution base or acid?
Sodium chloride is a salt; the water solution is neutral.
What will happen to pH if NaCI is added to pure water?
Adding NaCl to pure water will not have a significant effect on the pH of the solution. NaCl dissociates into Na+ and Cl- ions in water, which are pH-neutral, and do not affect the concentration of H+ ions in the solution.
