Does zinc react with citric acid?
Citric acid causes two chemical reactions with zinc- oxidation and reduction. Oxidation is where the acid removes the two electrons on the outer energy shell of each zinc atom. Reduction is where the hydrogen ions in the citric acid accept the electrons being released by the oxidation reaction and form the hydrogen gas. Hope this helps :)
What is the oxidation reduction potential of hydrogen?
Definition: The standard hydrogen electrode is the standard measurement of electrode potential for the thermodynamic scale of redox potentials.The standard is determined by the potential of a platinum electrode in the redox half reaction2 H+(aq) + 2 e- → H2(g) at 25 °C.The standard hydrogen electrode is often abbreviated SHE.Also Known As: normal hydrogen electrode or NHE
What evidence is there that hydrogen in hydrochloric acid is different from hydrogen in water?
The hydrogen in HCl has a metabolic concentration of solution with hydrogen which reacts with an aqueus solution in its anabolic form. This corresponds to hydrogen in water. The oxidation of the hydrogen in water is still positive 1 and it remains so therefore there is no redox reaction. Another argument can be made with the difference in the law of multiple proportions making the variable compoisiton with a ratio of solvent different. HCl undergoes a electronic blanace reduction causing the nucleus to emit a photon particle.

What is carbon reduction?
the process of carbon reduction is called carbon reduction process
Why Cr 2 plus is good reducing agent?
The reduction potential of the reaction Cr(3+)-------Cr(2+) is -0,41 V; the potential of hydrogen is zero so acids can be reduced with Cr(2+).
Define oxidation and reduction in terms of hydrogen transfer?
Oxidation and reduction in terms of hydrogen transferOxidation is loss of hydrogen.Reduction is gain of hydrogen.
Is hydrogen molecules to hydrogen ions an example of reduction?
No. It is oxidation.
What is the preparation of hydrogen?
The preparation of hydrogen gas is usually from a reduction of a compound containing hydrogen that is in the +1 oxidation state. This reduction is accomplished either electrically or chemically.
How many hydrogen atoms are in a molecule of reduction atoms?
There's no such thing as a "reduction atom".
Is hydrogen lost when a chemical reaction is a reduction?
NO
What is chemical reaction with hydrogen called?
reduction
How is a change in hydrogen ion concentration reflected in the pH?
pH is the negative logarithm of the hydrogen ion concentration; so an increase in hydrogen ion concentration give a reduction in pH. A reduction in hydrogen ion concentration causes an increase in pH.
What are oxidation and reduction reactions?
Oxidation can be generally loss of hydrogen, addition of oxygen or loss of electrons. Reduction can be generally addition of hydrogen, loss of oxygen or addition of electrons.
Is the conversion of an alkene to an alkane a reduction or an oxidation?
The addition of hydrogen on alkenes produces the alkanes so it is a reduction process.
Reduction is often referred to as?
Removal of oxygen , addition of hydrogen.
Which process during photosynthesis involves addition of hydrogen?
reduction...
What metal oxides can be converted to the metal by carbon reduction but not by hydrogen reduction?
any metals below carbon in the reactivity series. :)
