Borax is a good primary standard because it is a hydrated salt with a known chemical formula and molecular weight that can be easily determined. It can be dried to a constant weight and is stable in air, making it reliable for accurate titrations. Additionally, borax is readily available, affordable, and dissolves easily in water.

Is borax a primary standard?

No, borax is not considered a primary standard. Primary standards are highly pure reagents that can be used to standardize solutions for volumetric analysis, while borax is typically used as a secondary standard for acid-base titrations.


What are the three reasons why borax is a good primary standard?

High purity: Borax is readily available in high purity form, which makes it suitable as a primary standard for accurate titrations. Stability: Borax is stable in air and does not readily absorb moisture, ensuring consistency in its weight and concentration. Clear endpoint: Borax reacts readily with acids, producing a clear color change that signals the endpoint of the titration accurately.


WHY IS BORAX CONSIDERED A PRIMARY STANDARD?

Borax is considered a primary standard because it is a solid compound with a high degree of purity, a high molecular weight, and stable chemical properties. These characteristics make it suitable for accurately measuring the concentration of acids or bases in a titration procedure.


Why would NaOH not be used as a primary standard in the standardization of HCl with Borax?

Sodium hydoxide cannot be used as a primary standard because of its hygroscopic properties as a solid. Because it is so prone to absorbing water, it is impossible to accurately measure the mass of a solid sample, so instead it must be put into solution and tirated with a known acidic solution, such as HCl. This makes it a secondary standard as opposed to a primary standard. By. Kuatsienu Divine


When calculating the mass of borax needed to make up a standard solutiondo you ionclude 10h2o?

No, when calculating the mass of borax needed to make a standard solution, you do not include the water of hydration (such as the 10H2O). You only consider the anhydrous borax (without water molecules) in your calculations.

What are three reasons why borax is a good primary standard?

Borax has a high purity level, making it suitable for accurate and reproducible calibration. It has a stable chemical composition, which ensures consistent results over time. Borax is easily accessible, cost-effective, and not as sensitive to air and moisture as some other primary standards.

What is the theory of standardization of hydrochloric acid with Borax?

Borax can be used as a primary standard because it does not decompose in normal storage conditions. The salt will dissociate in water and the anion will be hydrolyzed. This leaves hydroxide ions to be titrated with the hydrochloric acid.

How much Borax should i use to take a bath in?

It is recommended to use 1-2 cups of borax in a standard-sized bathtub filled with warm water for a soothing bath. Make sure to dissolve the borax completely in the water before getting in. Avoid using borax baths if you have sensitive skin or any skin conditions.


Is k2cro4 a primary or secondary standard and why?

K2CrO4 is a secondary standard. This is because it is not directly titrated against a primary standard but rather is standardized by titration against a primary standard, such as sodium thiosulfate in iodometric titrations.


When you calculate the mass of borax needed to make up the standard solution do you include 10H2O?

No, when calculating the mass of borax needed for a standard solution, you only consider the anhydrous (water-free) form of the compound. The water molecules incorporated in the crystal structure are not included in the calculation of the mass.
