What else can I help you with?
Why you adding a methyl red in borax?
Methyl red is added to the borax solution to function as a pH indicator. It changes color at a specific pH range, which helps in determining the endpoint of the titration process when titrating an acid with the borax solution.
What color will turn after you mix red cabbage and borax?
The mixture is likely to turn blue due to the interaction between the anthocyanin pigments in red cabbage and the alkaline nature of borax.
What is the borax test of anthraquinons?
The borax test for anthraquinones involves mixing a sample with borax and heating it to produce a colored solution. The presence of anthraquinones is indicated by the color change in the solution. This test is commonly used to detect the presence of anthraquinones in organic compounds.
How about borax bead test?
The borax bead test is a qualitative analytical test used to identify certain metallic ions based on the color of the borax bead after heating with the sample. The test involves melting a small amount of borax with the sample on a platinum wire loop and observing the color of the resulting borax bead under a flame. Different metal ions produce distinct colored beads, aiding in their identification.
Why we used methyl red as indicator in titration borax with HCL?
Methyl red is used as an indicator in the titration of borax with HCl because it changes color in acidic conditions. This allows for the precise determination of the endpoint of the titration, which is when all of the borax has reacted with the acid. The color change indicates the shift from basic to acidic conditions, helping to stop the titration at the correct point.
Why flame of borax powder is color yellow?
The yellow color is from sodium radiation.
What color does borax turn in Universal indicator?
In Universal Indicator, borax typically changes to a greenish-blue color. This indicates a pH level around 9-10, which is alkaline.
What is colour of cobalt oxide in borax bead test?
Cobalt oxide typically appears as a blue color in the borax bead test.
What is the chemical equation for flame test for borax?
The chemical equation for the flame test for borax is: Na2B4O7·10H2O (borax) + heat → Na2O (sodium oxide) + B2O3 (boron trioxide) + H2O (water) + light emissions (color changes in flame)
Why you adding a methyl red in borax?
Methyl red is added to the borax solution to function as a pH indicator. It changes color at a specific pH range, which helps in determining the endpoint of the titration process when titrating an acid with the borax solution.
When litmus is added to a solution of borax it turns?
When litmus is added to a solution of borax, the litmus paper may turn blue due to the alkaline nature of borax. Borax is a weak base that can cause litmus paper to change its color from red to blue.
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 color will turn after you mix red cabbage and borax?
The mixture is likely to turn blue due to the interaction between the anthocyanin pigments in red cabbage and the alkaline nature of borax.

What colour would phenolphthalein go if added to borax solution?
Phenolphthalein would turn pink in a borax solution, indicating the solution is basic. Borax acts as a weak base in solution and would cause phenolphthalein to change color due to its alkaline nature.
