A 4 percent borax solution is a mixture containing 4 grams of borax (sodium borate) dissolved in 100 milliliters of water. This solution is often used for various purposes, including as a cleaning agent, a pesticide, or in laboratory settings. The concentration allows for effective use while being safe for various applications, depending on the intended use. Always handle borax with care, as it can be irritating in concentrated forms.

What is borax solution?
Borax solution is a mixture of borax (sodium borate) powder dissolved in water. It is commonly used as a cleaning agent, insecticide, and fungicide. Borax solution can also be used in certain scientific experiments and as a laundry booster.
How do borax crystals form?
Borax has a solubility of 5.8 grams per 100 milliliters of solution or 5.8 percent at room temperature. However at an elevated water temperature, more borax will dissolve than at room temperature. As the hot borax solution cools to room temperature, it becomes supersaturated. Supersaturated solutions are unstable and the excess borax will crystallize on any rough surface.
When litmus is added to a solution of borax?
When litmus is added to a solution of borax, it will turn blue. This indicates that the solution is basic or alkaline in nature. Borax, also known as sodium borate, is a weak base that can increase the pH of a solution.
What is the action of aqueous solution of borax on litmus paper?
Aqueous solution of borax is basic in nature and will turn red litmus paper blue. This is because borax can accept protons from water, making the solution basic.
Percent of boron in borax?
The percent composition of boron in borax (sodium tetraborate decahydrate) is approximately 11.3% by mass.
Why does borax mixed with hot water form crystals?
When borax is mixed with hot water, it dissolves forming a saturated solution. As the solution cools, the solubility of borax decreases, causing the excess borax to come out of the solution and recrystallize. This process forms crystals as the borax molecules arrange themselves in an organized structure to minimize energy.
How can crystles be growen out of just borax and boiling water?
Crystals can be grown from borax and boiling water by creating a supersaturated solution of borax in the water. As the solution cools, borax particles start to come together and form crystals. By allowing the solution to sit undisturbed for a period of time, large borax crystals will begin to grow.
How do make borax powder to liquid borax?
To make liquid borax, you can dissolve borax powder in hot water. Mix until the powder is fully dissolved and the solution becomes clear. Allow the solution to cool before using it.
Is borax solution an acid or a base?
It is both. It releases a steady amount of both as it dissolves.
Standardization of Hcl using Borax?
You can standardize a hydrochloric acid (HCl) solution using borax (sodium borate) by titrating a known concentration of HCl with a solution of borax. The reaction between HCl and borax can be used to determine the exact concentration of the HCl solution. By accurately measuring the volume of the titrant and using stoichiometry, you can calculate the concentration of the HCl solution.
Why is adding borax solution to glue a chemical change?
When you mix borax solution with glue, a chemical reaction occurs where the borax molecules crosslink the polymer chains in the glue. This leads to the formation of a new substance with different properties compared to the original glue and borax solution, constituting a chemical change.
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.
