What must be done to obtain the solid salt resulting from an acid - base reaction in an aqueous solution?
To obtain the solid salt resulting from an acid-base reaction in an aqueous solution, you can typically do so by evaporating the water from the solution. This will leave behind the solid salt that formed during the reaction between the acid and base. Once the water has evaporated, you can collect the solid salt for further use or analysis.

How you can make ammonium sulphate from aqueous ammonia and sulphuric acid?
Simply adding sulfuric acid to the ammonia solution will yield ammonium sulfate. The two will react naturally. Be sure to have your amounts and concentrations measured carefully so the reaction is as complete as possible. Pour the acid slowly as the reaction will be highly exothermic and may cause the solution to boil if not done carefully. The reaction equation is: H2SO4 + 2NH3 --> (NH4)2SO4
What amount of solid Naoh must be added to 750g of an aqueous solution to make 2.5 percent naoh solution by mass?
You would need to add 18.75g of solid NaOH to the 750g of aqueous solution to obtain a 2.5% NaOH solution by mass.
What happens when an aqueous solution of sodium sulphate reacts with an aqua solution of barium chloride?
The immediate response is a milky appearance. After 5-10 minutes a precipitate of BaSO4 will settle out of solution. You will obtain a cloudy, white precipitate that will remain so infantily. This is a precipitation reaction (the formation of an insoluble salt from a solution of soluble ones) which occurs because barium sulfate is insoluble, so when mixed, the barium ions react with the sulfate ions to form a white precipitate of barium sulfate The net ionic equation is: Ba2+(aq) + SO42-(aq) ----> BaSO4(s)
Sodium acetate from glacial acetic acid?
To prepare sodium acetate from glacial acetic acid, you can first neutralize the glacial acetic acid with sodium hydroxide. The reaction will yield sodium acetate and water. Afterward, you can evaporate the water to obtain solid sodium acetate crystals.
Which pieces of apparatus are needed to obtain solid lead iodide from 20cm3 of aqueous lead nitrate?
To obtain solid lead iodide from 20cm3 of aqueous lead nitrate, you would need a source of iodide ions (e.g., potassium iodide), a filtration apparatus to separate the solid lead iodide from the solution, a beaker or container to collect the solid, and a drying oven or desiccator to dry the collected solid. Optional equipment includes a stirring rod and a hot plate to facilitate the reaction.
How can we obtain potassium nitrate which is free of soil?
A simple method is to filter the aqueous solution; after this the solution is heated to obtain crystallized KNO3.

Copper(II) chromate can be prepared by reacting a solution of sodium chromate with a solution of copper(II) sulfate. The resulting precipitate is then filtered and dried to obtain solid copper(II) chromate.
Is running water through a filter considered a chemical change?
No, This is a process to obtain a solid from an aqueous solution. No chemical process is taking place during filtration.

What is the solution if you mixed the solute and solvent?
You obtain a solute solution in the desired and possible solvent.
What is a random error that can occur during an electrical conductivity in aqueous solution experiment?
A random error that can occur during an electrical conductivity experiment in an aqueous solution is fluctuations in temperature, which can affect the conductivity readings. Variations in the concentration of the solution due to evaporation or inaccuracies in measurement can also contribute to random errors. Additionally, inconsistent placement of the conductivity probe in the solution may lead to varying results. Such errors can introduce variability that makes it difficult to obtain precise and reproducible measurements.
Why sodium chloride is not in the aqueous state?
The reduction potential of sodium is under the same potential of water.
