On heating, borax first loses water molecules and swells up.On further heating it turns into a transparent liquid, which solidifies into glass like material known as borax bead.

What else can I help you with?
If you take borax and boiling water and make crystals is this a physical change or a chemical change?
It is a chemical change, because the borax reacts to the heated water.
What is the principle behind borax fusion test?
The bead of borax with some powdered sample is heated in a flame; the color of the bead is specific for each element and is used as a qualitative analysis.
What is na2BO3?
Na2BO3 is the chemical formula for sodium borate, also known as borax. It consists of sodium (Na), boron (B), and oxygen (O) and is commonly used in various applications, including as a cleaning agent, in glass and ceramics production, and as a flux in metallurgy. In addition, it has applications in agriculture as a micronutrient for plants. Sodium borate is typically encountered in its hydrated forms, such as borax decahydrate (Na2B4O7·10H2O).
How man boron atoms are in a molecule of borax?
There are 4 boron atoms in a molecule of borax (Na2B4O7·10H2O).
What happen when borex mix with cold water?
When borax is mixed with cold water, it dissolves and forms a solution. Borax is a water-soluble salt and will readily dissolve in water regardless of its temperature. The resulting solution can be used for various purposes, such as cleaning or as a laundry booster.
What happen when borax is heated strongly?
When heated borax undergoes various transitions,first it loses water molecules and swells,then it turns into a transparent liquid solidifying to for a glass like structure called borax beads. Na2B4O7.10H20 -->heating Na2B4O7 -->heating 2NaBO2 + B2O3 BORAX SODIUM BORIC METABORATE ANHYDRIDE
What happen when borax is heated with CaO?
When borax is heated with CaO, the borax is decomposed to form sodium metaborate and calcium metaborate. This reaction is usually used in analytical chemistry to detect the presence of boron in a sample.
How many hydrogen atoms are in a molecule of borax?
The borax decahydrate - Na2B4O7.10 H2O has 20 H atoms in the molecule.
What will happen if borax was on your arm?
Borax is harmless.
What happens when borax is heated?
When heated borax undergoes various transitions,first it loses water molecules and swells,then it turns into a transparent liquid solidifying to for a glass like structure called borax beads. Na2B4O7.10H20 -->heating Na2B4O7 -->heating 2NaBO2 + B2O3 BORAX SODIUM BORIC METABORATE ANHYDRIDE
Balanced equation of Hydrated borax and HCl reaction?
The balanced equation for the reaction between hydrated borax (Na2B4O7·10H2O) and hydrochloric acid (HCl) is: Na2B4O7·10H2O + 2HCl → 4B(OH)3 + 2NaCl + 5H2O
If you take borax and boiling water and make crystals is this a physical change or a chemical change?
It is a chemical change, because the borax reacts to the heated water.
Give equations to represent the following reactions.(a) Borax is heated with CaO?
The chemical equation to represent the reaction between borax (Na2B4O7) and CaO (calcium oxide) when heated is: Na2B4O7 + CaO → CaB4O7 + Na2O In this reaction, borax and calcium oxide react to form calcium tetraborate (CaB4O7) and sodium oxide (Na2O) as the products.
What is the principle behind borax fusion test?
The bead of borax with some powdered sample is heated in a flame; the color of the bead is specific for each element and is used as a qualitative analysis.
Why borax is a good primary standard?
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.
Why does borax burn green?
Borax burns green due to the presence of boron in its chemical composition. When borax is heated, the electrons in the boron atoms are excited to higher energy levels, and as they return to their original state, they emit green light. This phenomenon is known as green flame emission.
How does boiling water dissolves borax and why?
When water is heated to its boiling point, the kinetic energy of the water molecules increases, allowing them to overcome the intermolecular forces holding the borax particles together. This increased kinetic energy helps break down the ionic bonds in borax, allowing it to dissolve in the water.
