Why is NaCl an aqueous solution?
The molecules that dissolve in the solvent are called the solutes. Therefore, in a solution of salt (NaCl) and water, the water is the solvent and the sodium and chloride are the solutes. A solution in which water is the solvent is called an aqueous solution.
Is an aqueous solution of NaCl acidic basic or neutral?
neutral
It is neutral in nature.
What are the products of aqueous NaCl?
The product of electrolysis of concentrated aqueous sodium chloride are sodium hydroxide, hydrogen gas and chlorine gas.
How do you make a NaCl aqueous solution?
Fill a flask with 0.8 liters of water, weigh out the amount of sodium chloride you need, add it to the water and shake until it dissolves. To make a 1M solution, add 58.44 grams of salt; to make a 0.1M solution, add 5.84 grams; to make a 2M solution, add 116.88 grams and so on.
Is NaCl aqueous in water?

What is an aqueous solution example?
An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as Na +(aq) + Cl −(aq).
What is the nature of aqueous solution of salt?
An aqueous solution of a salt has basic nature.
What is the pH of NaCl solution?
to 7
Thus, the aqueous sodium chloride solution is a neutral solution with equal concentration of hydronium ions and hydroxide ions. Aqueous sodium chloride solution has pH equal to 7.
When aqueous solution of NaCl is electrolyte a product formed at the cathode is?
H2 gas
If an aqueous solution of NaCl is electrolysed, the product obtained at the cathode is H2 gas and not Na .
What happens during the electrolysis of an aqueous NaCl solution?
When an electric current is passed through concentrated sodium chloride solution, hydrogen gas forms at the negative electrode , chlorine gas forms at the positive electrode, and a solution of sodium hydroxide also forms.
How do you make an aqueous solution?
How to make an aqueous solution
- Step 1: Calculate the mass of the compound needed to achieve a specific molar concentration and volume.
- Step 2: Weigh and measure.
- Step 3: Combine the solute and solvent.
- Step 4: Adjust the pH of the solution.
- Step 5: Bring the solution to final volume.
- Dilutions for complex solutions.
What is 0.1M solution?
To make a 0.1M NaCl solution, you could weigh 5.844g of NaCl and dissolve it in 1 litre of water; OR 0.5844g of NaCl in 100mL of water (see animation below); OR make a 1:10 dilution of a 1M sample.
What is meant by an aqueous solution?
An aqueous solution is one in which the solvent is liquid water. That is, solute (dissolved) ions and molecules are surrounded by water molecules and incorporated into the network of bonds within the water. The dissolved species then spread throughout the water.
What are three examples of an aqueous solution?
Some examples of aqueous solutions are cola, saltwater, rain, acid solutions, base solutions, salt solutions, etc. Some examples of solutions that are not aqueous solutions include any liquid that does not contain water.
Is NaCl aqueous or solid?
NaCl(s) is the solid form. NaCl(aq) is the aqueous form, which means that the solid was is dissolved in water, and is now an aqueous solution.
What is the nature of NaCl solution?
NaCl is salt in nature because when NaCl is dissolved in an aqueous solution it breaks apart into two ions i.e. Na+ and Cl–. These ions are extremely weak acid and base in nature so neither of them is capable of hydrolyzing. As a result, the pH of an aqueous solution containing the ions of NaCl remains neutral.
How do you identify an aqueous solution?
Is NaCl strong or weak acid?
NaCl is salt in nature because when NaCl is dissolved in an aqueous solution it breaks apart into two ions i.e. Na+ and Cl–. These ions are extremely weak acid and base in nature so neither of them is capable of hydrolyzing. As a result, the pH of an aqueous solution containing the ions of NaCl remains neutral.
What is the pH of NaCl in water?
Therefore, by the calculations, it is proved that the pH of sodium chloride when dissolved in water at room temperature i.e at 25°C, is equal to 7.
When electricity passes through NaCl aqueous solution what happens?
When an electric current is passed through an aqueous solution of sodium chloride, sodium ions move towards cathode and chloride ions move towards anode.
When an aqueous solution of NaCl is Electrolysed?
If an aqueous solution of NaCl is electrolysed, the product obtained at the cathode is H2 gas and not Na .
When aqueous solution of NaCl is Electrolysed the product obtained at cathode is?
What happens at anode during electrolysis of aqueous NaCl?
a) The electrolysis of aqueous NaCl produces hydrogen gas at the cathode and chlorine gas at the anode .
What is aqueous solution example?
What is a basic aqueous solution?
A basic solution is an aqueous solution containing more OH-ions than H+ions. In other words, it is an aqueous solution with a pH greater than 7. Basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.
