Why is water considered the universal solvent?(1 point)
Water molecules are held together by covalent bonds.
.Water is a polar compound because its ends have opposite charges.
Water molecules are weakly bonded to other water molecules.
Water dissolves more substances than any other solvent.
Water is considered the universal solvent because it is a polar compound due to its opposite charges on each end. This polarity enables water molecules to easily break apart and surround other charged or polar molecules, effectively dissolving them. As a result, water is able to dissolve more substances than any other solvent.
The main reason why water is considered the universal solvent is because it is a polar compound. This means that its ends have opposite charges. The oxygen atom in water attracts the electrons of the hydrogen atoms, creating a partial negative charge near the oxygen and partial positive charges near the hydrogen atoms. This polarity allows water molecules to attract and surround other charged or polar molecules, effectively dissolving them. As a result, water is able to dissolve more substances than any other solvent. Therefore, the correct answer is: Water is a polar compound because its ends have opposite charges.
Water is considered the universal solvent because it has the ability to dissolve a wide variety of substances. One point that supports this is that water is a polar compound because its ends have opposite charges. This polarity of water molecules allows them to interact with other polar molecules, such as salts or sugars, by attracting and surrounding them, causing the molecules to dissociate and dissolve in the water.
To understand why water is considered the universal solvent, it is important to have a basic understanding of the concept of solubility. Solubility refers to the ability of a substance (solute) to dissolve in another substance (solvent) to form a homogenous mixture called a solution.
Water is a polar molecule, meaning it has a positive charge on one end and a negative charge on the other due to the unequal distribution of electrons. This polarity arises from the bent shape of the water molecule and the electronegativity difference between oxygen and hydrogen atoms.
When a solute dissolves in water, the positive end of water molecules, which is attracted to negatively charged species, interacts with the negatively charged particles in the solute. On the other hand, the negative end of water molecules, which is attracted to positively charged species, interacts with the positively charged particles in the solute. This results in the separation of solute particles and their dispersion throughout the water, leading to the dissolution of the solute.
Additionally, water molecules are weakly bonded to other water molecules through hydrogen bonds. These hydrogen bonds make water an excellent solvent because they provide a relatively strong attraction between water molecules, allowing for the easy movement and dispersion of solute particles.
Another reason why water is considered the universal solvent is that it has a high dielectric constant. The dielectric constant indicates how well a solvent can separate and disperse ions. Water has a high dielectric constant, which means it has a greater ability to dissolve ionic compounds, such as salts. The positive and negative ends of water molecules are able to surround and separate the ions, effectively dissolving the salt.
Considering all of these factors, water's ability to dissolve a wide range of solutes, including both polar and ionic compounds, makes it the universal solvent.
