How do I identify acid-base reactions and redox reactions?

Answer 1

These reactions are not mutually exclusive...........

#NaH(s) + H_2O(l) rarr NaOH(aq) + 1/2H_2(g)uarr#

As stated, the hydride anion has reduced the water molecule to produce dihydrogen, making this an acid-base reaction as well as a redox reaction.

In general, any reaction in which oxidation states change (and fuel oxidation falls under this umbrella) are in fact #"redox reactions"#.

Could you give this combustion's formal oxidation states?

#CH_4(g) + 2O_2(g) rarr CO_2(g) + 2H_2O(l)#
Hint, carbon is more electronegative than hydrogen, and hence assumes a formal #C^(-IV)# state in #"methane"#. The oxidation state of hydrogen in #"dihydrogen gas"# is #0#.

Answer 2

To identify acid-base reactions, look for the transfer of protons (H⁺ ions) from one substance to another. In acid-base reactions, acids donate protons to bases, forming water and a salt. In redox reactions, identify the transfer of electrons between reactants. Oxidation involves the loss of electrons, while reduction involves the gain of electrons. Redox reactions often involve changes in the oxidation states of elements.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
