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.

Why is non hygroscopic important for primary standard?
Then it is possible to measure accurately the weight of it, so you know exactly how many moles of the primary standard you have. When it would have been hygroscopic then your actual mass of the standard is lower than the measured, caused by the extra weight of water.
Can you use borax in biguanide pool?
Not recommended. For what purpose would you intend to use the Borax? This is not a regularly used product for pools in most areas of the country.
What colour would phenolphthalein go if added to borax solution?
it's pink
What is the process of standardization?
Standardization is a term that can be used in many fields. A chemist would use standardization when trying to figure out the concentration of an unknown solution. They need to know the specific concentration of one of the solutions so they can calculate the other unknown concentration. Many acid-base reactions use this technique. They perform a series of repeatable tests with a third chemical solution that never varies in concentration. They can then calculate the one concentration and use it in their experiment to determine the other concentration. This set of tests is known as standardization of a solution.
Is borax toxic to cats?
I have used borax to successfully treat a flea infestation in my house. I have 13 cats and 4 dogs and none have had any ill effect from the borax. I have not left it on the carpeting for more than a few hours before vacuuming it up again, however.The MSDS (material safety data sheet) for borax states "WARNING! HARMFUL IF SWALLOWED, INHALED OR ABSORBED THROUGH SKIN. CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT."I would err on the side of caution and not use it directly on your cats.
Will borax kill centipedes?

Would an organic substance effect the solubility of borax?
No
What is the difference betwen borax and flour?
Borax and flour are both white powders, but are very different! Borax is a natural mineral with a chemical formula Na2B4O7 • 10H2O. It is used as a cleaning agent, either in laundry detergent, or household cleaners. There is debate on the safety of ingesting borax, but it is something you would want to avoid eating. Flour is made by grinding grains, beans, seeds, or roots and is the primary ingredient used in making bread. Flour is absolutely safe to eat, and is found in many different foods!
Can you replace borax with tide powder when making slme?
No. Borax is sodium borate. Tide powder is not, so it would not act the same.

Is Borax safe for the environment?
* No. It is a strong alkaline and will kill many organisms. That is why it is added to laundry detergent to kill off bacteria. * I'm not a fan of borax and own a business that uses objective criteria to judge if a cleaning chemical is truly green (borax would not meet the criteria), but as a chemist I can hardly call borax, with a pH in water of 9.5, a strong alkaline. It does dissociate well, but we're not talking sodium hydroxide, which is a strong alkaline with a pH of nearly 13. Borax is also a decent surfactant which is why I understand it's used in laundry detergents. It dissolves readily. Borax can be used as a pesticide. * Yes it is safe for the environment. Borax is a naturally occurring mineral and consists of water, sodium, boron and oxygen. See link below. * Note-Borax is often recommended as a "safe" pesticide, fungicide, arts and crafts material and cleaner, but it is officially classified as a poison by the FDA.
