A solution is a homogeneous mixture composed of only one phase. In such a mixture, a solute is a substance dissolved in another substance called as the solvent. The concentration of a solute in a solution is a measure of how much of that solute is dissolved in a solvent.
Standard solutions are those in which the exact amount of a substance presents in a definite volume of solution. To prepare the standard solution, a known weight of solute is measured on a well-calibrated weighing scale and then dissolved in a solvent (usually distilled water) to make up a specific volume.
Normality (N) is one of the commonly used units that determine the concentration of the solution that expresses the gram equivalent weight of solute per liter of the solution. In other words, Normality is simply the number of active grams of a solute per liter of the solution.
The 0.1 N Sodium Carbonate solution is prepared as follows…..
MATERIAL REQUIRED…..
Weighing scale
Beaker/Volumetric flask
Stirrer
Measuring cylinder
CHEMICALS REQUIRED…..
Sodium Carbonate (Na2CO3)
Distilled water
CALCULATIONS…..
Molecular weight of Na2CO3 – (23×2) + 12 + (3×16) = 46 + 12 + 48 = 106 gm
Normality = Weight / Equivalent weight × 1000 / Volume (in ml)
0.1 = (X/106/2) × (1000 / 500)
0.1 = (X × 2 / 106 ) × (1000 / 500)
X = 0.1 × 53 × 0.5 = 2.65 gm
X = 2.65 gm
PROCEDURE…..
⇒ Weigh 2.65 gm of Na2CO3 with the help of weighing scale.
⇒ Then take 200 ml of distilled water in Beaker / Volumetric flask and to this add 2.65 gm of Na2CO3.
⇒ If using a beaker, mix the contents well by using a stirrer and If using the Volumetric flask mix well the contents by gently swirling the flask.
⇒ When it dissolves completely then add the Distilled water and make the final volume of 500 ml.
⇒ Then again mix it with the help of stirrer in case of the beaker or by swirling in case of volumetric flask.
PRECAUTIONS…..
⇒ Weigh accurately 2.65 gm anhydrous Sodium Carbonate on a well-calibrated weighing balance.
⇒ Last few milliliters of the distilled water should be added using a pipette to avoid volume error.
⇒ Transference of the weighed substance into a beaker or volumetric flask should be done very carefully and not a single crystal be allowed to fall outside.
⇒ Sodium carbonate solutions are strongly alkaline and corrosive. It can cause severe skin and eye irritation upon contact.
⇒ Inhalation of sodium carbonate dust or fumes can cause irritation of mucous membranes and the respiratory tract, and lead to severe coughing and shortness of breath. High concentrations can damage the eye and cause skin burns.
Preparation of sodium carbonate:
- An answer is a homogeneous combination composed of the most effective phase. In any such combination, a solute is a substance dissolved in any other substance known as the solvent.
- The awareness of a solute in an answer is a degree of ways a lot of that solute is dissolved in a solvent.
- Standard answers are the ones wherein the precise quantity of a substance affords a particular extent of answer.
- To put together the usual answer, an acknowledged weight of solute is measured on a properly-calibrated weighing scale after which dissolved in a solvent (generally distilled water) to make up a particular extent.
- Normality (N) is one of the usually used gadgets that decide the awareness of the answer that expresses the gram equal weight of solute in line with the liter of the answer.
- In different words, Normality is genuinely the number of lively grams of a solute in line with the liter of the answer.
The 0.1 N Sodium Carbonate answer is ready as follows:
Materials Required: Weighing scale, Beaker/Volumetric flask, Stirrer, Measuring cylinder
Chemicals Required: Sodium Carbonate (Na2CO3), Distilled water
Calculations:
- Molecular weight of Na2CO3 – (23×2) + 12 + (3×16) = 46 + 12 + 48 = 106 gm
- Normality = Weight / Equivalent weight × 1000 / Volume (in ml)
- 0.1 = (X/106/2) × (1000 / 500)
- 0.1 = (X × 2 / 106 ) × (1000 / 500)
- X = 0.1 × 53 × 0.5 = 2.sixty five gm
- X = 2.sixty five gm
- Procedure:
- ⇒ Weigh 2. sixty-five gm of Na2CO3 with the assistance of a weighing scale.
- ⇒ Then take two hundred ml of distilled water in Beaker / Volumetric flask and to this upload 2. sixty-five gm of Na2CO3.
- ⇒ If the use of a beaker, blend the contents properly with the aid of using the use of a stirrer, and If the use of the Volumetric flask blends properly the contents with the aid of using lightly swirling the flask.
- ⇒ When it dissolves then upload the Distilled water and make the very last extent of 500 ml.
- ⇒ Then once more blend it with the assistance of a stirrer withinside the case of the beaker or with the aid of using swirling it withinside the case of a volumetric flask.
Precautions:
- ⇒ Weigh as it should be 2. sixty-five gm anhydrous Sodium Carbonate on a properly-calibrated weighing balance.
- ⇒ Last few milliliters of the distilled water must be delivered by the use of a pipette to keep away from extent error.
- ⇒ Transference of the weighed substance right into a beaker or volumetric flask must be accomplished very cautiously and now no longer an unmarried crystal allowed to fall outside.
- ⇒ Sodium carbonate answers are strongly alkaline and corrosive. It can motivate intense pores and skin and eye infections upon contact.
- ⇒ Inhalation of sodium carbonate dirt or fumes can motivate infection of mucous membranes and the respiration tract, and cause intense coughing and shortness of breath. High concentrations can harm the attention and motive pores and skin burns.
