When NaOHaq reacts completely with HCLaq and the resulting solution is evaporated to dryness the solid remaining is?
Sodium chloride (NaCl) would be left behind after evaporating the solution to dryness. This is because when sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl), it forms sodium chloride and water. Evaporating the water leaves behind solid sodium chloride.
Is it a physical change or a chemical change when a filtrate is evaporated to dryness?
Evaporating a filtrate to dryness is a physical change because it involves the phase transition of a liquid (filtrate) to a gas (water vapor) without changing the chemical composition of the substance.
When 125 grams of solution was evaporated to dryness. 14.3 grams of solute was recovered what was the percentage of the solute?
The percentage of solute in the solution is calculated by dividing the mass of the solute recovered (14.3g) by the initial mass of the solution (125g) and then multiplying by 100. Percentage of solute = (14.3g / 125g) * 100 = 11.44%, or approximately 11.4%.
What would happen if an aqueous solution of sugar is heated to dryness?
Crystals of sugar are obtained.
Why should you not heat a solution to dryness in an evaporating dish?
Well, friend, heating a solution to dryness in an evaporating dish can be risky because it can lead to the dish becoming too hot and causing the solution to splatter or even the dish to crack. It's like trying to rush a beautiful painting - patience is key in the lab just like it is on the canvas. It's best to gently evaporate the solution using low heat to avoid any accidents and ensure a safe and successful experiment.

What residue is form when formalin was evaporated to dryness?
formaldehyde

What will happen to formalin when evaporated to dryness on a water bath?
When formalin is evaporated to dryness on a water bath, the water content will gradually evaporate, leaving behind a residue of formaldehyde and other components present in the solution. The formaldehyde may polymerize into paraformaldehyde, a solid polymer, upon concentration. This process can release vapors of formaldehyde, which are hazardous and require proper ventilation. Care should be taken to avoid overheating, as it can lead to decomposition and the release of toxic gases.
Which piece of laboratory apparatus would most likely be used to evaporate a 1-milliliter sample of a solution to dryness?
Which piece of laboratory apart it would most likely be used to evaporated E1 millimeters sample of a solution to drynes
What is heating to dryness mean?
Heating a solution until all the solvent has evaporated is known as heating to dryness.
How we obtain pure potassium nitrate which is free of soil?
Pure potassium nitrate can be obtained by dissolving a source of potassium nitrate, such as KNO3 crystals, in water and then filtering the solution to remove any soil or impurities. The filtered solution can then be evaporated to dryness, leaving behind pure potassium nitrate crystals.

If 50 grams of water satured with potassium chlorate 23 Celsius is slowly evaporated to dryness how many grams of the dry salt will be recovered?
If 50 grams of water saturated with potassium chlorate at 23 degrees Celsius is slowly evaporated to dryness, approximately 6.5 grams of the dry salt (potassium chlorate) would be recovered. This is based on the solubility of potassium chlorate in water at that temperature.
How can you get pure dry crystals of sodium chloride from a solution of sodium chloride in watere?
Evaporating to dryness
Can you obtain pure calcium nitrate crystals by evaporating the solutions to dryness?
Yes, you can obtain pure calcium nitrate crystals by evaporating the solution to dryness. As the water evaporates, calcium nitrate will start to crystallize out of the solution. To ensure purity, it is important to start with a pure calcium nitrate solution and use distilled water for evaporation.
