What else can I help you with?
How much water must be added to 425 g of formaldehyde to prepare a 40.0 percent by mass solution of formaldehyde?
To calculate the amount of water needed, first determine the mass of formaldehyde in the final solution. Since the solution is 40.0% formaldehyde by mass, the mass of formaldehyde is 40.0% of the final solution mass. Subtract the mass of formaldehyde in 425 g from this value to find the mass of water needed to prepare the solution.
What type of matter is formaldehyde correctly classified?
Formaldehyde, HCHO, is an example of an aldehyde (or carbonyl compounds)
A substance that does not dissolve in a solvent is said to be what in that solvent?
- Sand does not dissolve in water- Plastic does not dissolve in water- metals do not dissolve in water
How is formalin produced?
Formalin is produced by mixing formaldehyde gas with water to form a solution of formaldehyde in water. The reaction is generally carried out in the presence of a catalyst, such as a base or an acid, to enhance the speed of the reaction.
What is the melting point of formaldehyde?
The melting point of formaldehyde is approximately -80.1 degrees Celsius (-112.2 degrees Fahrenheit). At this temperature, formaldehyde transitions from a solid to a liquid state. In its common form as a gas, formaldehyde is typically encountered at room temperature, but it can be stored as a solution in water or as solid paraformaldehyde.
Do H20 and CH20 dissolve in each other and why?
No, H2O (water) and CH2O (formaldehyde) do not easily dissolve in each other because they have different chemical structures and polarities. Water is a polar molecule due to its unequal sharing of electrons, while formaldehyde is a nonpolar molecule, resulting in a weak interaction between the two substances.
What is formalin?
Formaldehyde is a mixture of 40% formaldehyde, 8% methyl alcohol and 52% water.
What is molecular formula of formalin?
A 37% aqueous (water) solution of formaldehyde. The molecular formula of water is H2O and of formaldehyde is CH2O.
Why does mm melt with water?
Melamine formaldehyde (also known as Melamine) is a type of plastic resin that is water-soluble. When the melamine compound comes in contact with water, the hydrogen bonds between the water molecules disrupt the weak forces holding the melamine molecules together, causing it to dissolve or "melt" in the water.
What is the composition of formalin?
Formalin is a saturated solution of formaldehyde, water, and typically another agent, most commonly methanol. In its typical form, formalin is 37% formaldehyde by weight (40% by volume), 6-13% methanol, and the rest water.

What is difference between formaldehyde and formalin?
They are essentially the same thing. Formalin is the histologist's term for a solution of formaldehyde stabilized with a small percentage of methanol. In fact any aqueous solution of formaldehyde probably contains trace MeOH. Such solutions would make effective (but very messy) surface disinfectants. Formaldehyde is probably used more often to disinfect equipment in a fumigation-type process, where a closed space is filled with formaldehyde vapor. I think this is done by heat-sublimation of solid para-formaldehyde.
How can I effectively remove formaldehyde from clothes?
To effectively remove formaldehyde from clothes, you can try washing them with a mixture of water and baking soda, or soaking them in a solution of vinegar and water. Additionally, hanging the clothes outside in fresh air and sunlight can help to naturally dissipate the formaldehyde.

Does water and salt dissolve?
No, but salt does dissolve in water.
