What is the reduction of water half reaction?
The reduction of water half reaction involves the gain of electrons by water molecules, leading to the formation of hydrogen gas and hydroxide ions.
Which equation best represents the dissociation of watermark molecules into hydrogen ions and hydroxide ions?
The dissociation of water molecules into hydrogen ions and hydroxide ions is best represented by the equation: H2O -> H+ + OH-.
What happens to the concentration of hydrogen ions when an acid and a base are reacted?
The concentration of hydrogen ions decreases as they react with hydroxide ions from the base to form water molecules.
Is electrolysis of water to form hydrogen and oxygen a physical or chemical change?
It is a chemical change because you are breaking the water into its elements, hydrogen and oxygen, and it is no longer water. I NEED THE NUMBER'S ^ Here They are Oxidation of ions or neutral molecules occurs at the anode, and the reduction of ions or neutral molecules occurs at the cathode. For example, it is possible to oxidize ferrous ions to ferric ions at the anode:Fe2+ aq → Fe3+ aq + e- It is also possible to reduce ferricyanide ions to ferrocyanide ions at the cathode:Fe(CN)3- 6 + e- → Fe(CN)4- 6
What types of enzymes remove hydrogen atoms from its substrate?
Oxidoreductases, particularly dehydrogenases, are enzymes that remove hydrogen atoms from their substrate by catalyzing oxidation-reduction reactions. These enzymes play a crucial role in metabolism by transferring electrons and hydrogen ions between molecules.
What two molecules are formed by the Hydrogen ions?
Hydrogen ions can form water molecules (H2O) by combining with hydroxide ions (OH-) or hydronium ions (H3O+).
What is the reduction of water half reaction?
The reduction of water half reaction involves the gain of electrons by water molecules, leading to the formation of hydrogen gas and hydroxide ions.
Will the hydrogen ion always combine with a water molecule?
No, hydrogen ions can combine with other molecules or ions besides water. For example, hydrogen ions can combine with hydroxide ions to form water, or they can bond with substances like ammonia or carbonates.
What is the difference between activation polarization and concentration polarization?
Activation polarization refers to a condition when the reaction rate (of oxidation or reduction) is controlled by the slowest "step" in a series of reaction steps. For example, in hydrogen reduction reaction, the first step (1) may be when hydrogen ions absorbed from solution onto the anode surface, (2) then electron transfer occurs from anode to the hydrogen ions to form hydrogen, (3) then the hydrogen elements form hydrogen gas molecules, (4) which then form hydrogen gas bubbles. The slowest of these 4 steps, dictates how fast the overall reduction reaction happens. Concentration polarization refers to a condition of the limits of diffusion. Basically, again referring to the hydrogen reduction reaction, the concentration of H+ ions around the cathode affects the reaction rate. It could be that the concentration is too high (there is plently of H+ ions around, or the concentration is too low (not enough H+ ions around or the reduction reaction is 'eating them up' too quickly).
Which equation best represents the dissociation of watermark molecules into hydrogen ions and hydroxide ions?
The dissociation of water molecules into hydrogen ions and hydroxide ions is best represented by the equation: H2O -> H+ + OH-.
Is hydrogen a ion or a molecule?
Hydrogen exists on Earth mostly as part of molecules. Those molecules can be electrically neutral, or they can be ions.
What happens to the concentration of hydrogen ions when an acid and a base are reacted?
The concentration of hydrogen ions decreases as they react with hydroxide ions from the base to form water molecules.

Can a positively charge hydrogen ends of water molecules attract chloride ions?
Yes, the positively charged hydrogen ends (or hydrogens) of water molecules can attract negatively charged chloride ions. This attraction occurs due to the electrostatic forces between the opposite charges, leading to the formation of hydrogen bonds between water molecules and chloride ions.
What is the initial cause of the dissociation of water molecules into hydrogen and hydroxide ions?
The initial cause of the dissociation of water molecules into hydrogen and hydroxide ions is the breaking of the hydrogen-oxygen bonds within the water molecule due to thermal energy. This process is facilitated by the natural tendency of water molecules to ionize into H+ and OH- ions.
Why are hydrogen ions attratected to water molecules?
Hydrogen ions are attracted to water molecules because water is a polar molecule with a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. The positive hydrogen ions are attracted to the negative oxygen atoms in water through electrostatic forces, forming hydrogen bonds that stabilize the system.
