it says oxygen acts negativw so most likely hydrogen on the bottom acts positive

Substances that dissolve in water?

substances that dissolve in water include, sugar, salt and others.


How does salt dissolve in water?

The water molecule is polar. The oxygen and hydrogen atoms do not share the electrons equally. The larger oxygen atom tends to hold the electrons more closely than the hydrogen atoms. This causes the oxygen end of the water molecule to be slightly negatively charged, and the hydrogen atoms to be slightly positively charged. When a salt is added to water, the slightly positive hydrogen atoms attract the negative ions of the salt, and the slightly negative oxygen atom attracts the positive ions of the salt, causing them to dissociate and dissolve in the water.


Why do water and Fat not mix?

water is charged positively on the oxgen end, and negativelyon the hydrogen end. Oil does not have a charge ( it's netrual), so the oil does not mix with the water. (EDIT by Dr.J.) - Close, but actually water is charged NEGATIVELY on the oxygen and POSITIVELY on the hydrogen. So, it is POLAR, and oil is not polar, so they don't "mix".


Is urea hydrophobic?

Urea is a water-soluble compound with a formula of (NH2)2CO , found in urine. Hydrophobic indicates a molecule that is non-polar, and therefore insoluble in water, so Urea is not hydrophobic.


What are the partial charges in a water molecule?

The Oxygen molecule and Hydrogen molecules have different electronegativity (due to position on Periodic Table). As Oxygen is more electronegative it draws the negatively charged electrons towards itself. This makes the hydrogen atoms more positive and hence the partial charges.

Is water a negatively or positively charged molecule?

Water is a neutral molecule, meaning it does not have a positive or negative charge overall.


Is solute molecule negatively charged in water?

Not necessarily. Solute molecules can be neutral, positively charged, or negatively charged in water. The charge of the solute molecule depends on its chemical structure and the presence of any functional groups that can interact with water molecules.


What makes a water polar molecule?

The ends of the water molecule have opposite electrical charges


What major property of water helps it hold molecules together?

Water is a "polar" molecule; one end of the molecule is negatively charged while the other end is positively charged.


How is water an example of polar molecule?

The oxygen atom, which is negatively charged, is on one end ("pole") of the molecule, and the hydrogen atoms, which are positively charged, are on the other pole.


Is water negatively charged or positively charged?

Water is a neutral molecule, meaning it has no net charge. The oxygen atom in a water molecule has a slight negative charge, while the hydrogen atoms have a slight positive charge, but overall the molecule is neutral.


What is the over all change on a water molecule?

The overall charge on a water molecule is neutral because it contains an equal number of positively charged protons and negatively charged electrons. Each water molecule consists of two positively charged hydrogen atoms and one negatively charged oxygen atom, resulting in a balanced charge overall.


Is water positively charged or negatively charged?

Water is neutrally charged. It has H+ and OH- ions. 1 positive and 1 negative charged ion. The positive and negative ions cancel each other out and therefore we end up with a neutrally charged water atom.


What charge does a molecule have?

Solute molecules can be positively charged, negatively charged, or neutral. For example, dissolving sodium chloride in water produces positively charged sodium cations and negatively charged chloride anions. Dissolving sucrose (table sugar) in water produces only dissolved neutral sucrose molecules.


What is A molecule with one end positively charged and one end negatively charged?

A molecule with one end positively charged and one end negatively charged is called a polar molecule. This charge separation is due to differences in electronegativity between the atoms in the molecule, leading to an uneven distribution of electrons. Water is a common example of a polar molecule.


What type of bond holds one water molecule to another water molecule?

A hydrogen bond holds one water molecule to another water molecule. This type of bond occurs between the positively charged hydrogen atom of one water molecule and the negatively charged oxygen atom of another water molecule.


Why is covalent bonds polar?

There are two hydrogen atoms. Hydrogen is positively charged. That means that there is a 2+. There is one oxygen atom. Oxygen is negatively charged. This means that there is a 1-. (2+) - (1-) = 1+ charge A water molecule is polar because one side of the molecule is positively charged and the other is negatively charged due to it's molecular structure.
