Calculating molarity and factor of HCl and Borax solutions in standidization?
Factor in hcl ?
Balanced equation of Hydrated borax and HCl reaction?
b4o7+hcl=b4hcl+h20
Standardization of hydrochloric acid with borax?
Dissolve approximately 0.25g of Borax in distilled water. Titrate against hydrochloric acid using methyl orange indicator. At end-point, solution should be almost colourless against a white background.
Why is HCl not used as catalyst in the standardization of potassium permanganate?
because it is dilute in nature
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

Products formed when na2b4o7.10h2o hcl reacted?
Na2B4O7.10H2O (borax) + 2HCl ---> 2NaCl + 4H3BO3 + 5H2O
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.

Why do you keep the flask in dark during standardization of na2s2o3 using k2cr2o7?
why flask keep in dark during standardization of na2s2o3 using k2cr2o7
How do you make slime using borax?
mix water with borax, and then a touch of saliva
Standardization of hcl solution with primary standard na2co3 solution?
solution containig (3.3)gm na2co3 .h2o in (15ml)
What is the balanced equation for and HCl and Borax?
The over all equation is, 2HCl + Na2B4O7.10H2O = H2B4O7 + 2NaCl + 10 H2O
Why standardization is critical activity?
Standardization is critical activity for communication of results.If communication is not important, Standardization is not important.Everyone can create their own symbols and things will work just as well.A Satellite failed because some engineers were using foot pounds and others were using joules.
