In which of the three acid-base concepts can water be a product of an acid-base reaction? In which is it the only product?
Archy [21]

Salt and water is formed as product, when Arrhenius acid and Arrhenius base reacts and the reaction is known as neutralization reaction.

<h3>What is Arrhenius acid-base reaction?</h3>
  • The concept of acid and base based on the theory of ionization which was first proposed in 1884 by Svante Arrhenius
  • According to Arrhenius, on dissociation in water the hydrogen-containing compounds which give H+ ions or protons are the acids and  the hydroxide compounds which give OH− ions on dissociation in water are bases.
  • This theory is applicable only to compounds which are dissolved in aqueous solution.

At what pH are the moles of acid and base equal?
mihalych1998 [28]

Answer:

7

Explanation:

(Note: for a strong acid and strong base titration the equivalence point is at a pH=7. This is because at this point you have equal moles of added base as acid in the original solution. Therefore at the equivalence point the solution has formed a neutral salt and the pH is 7).

For the following reactions, write a balanced equation using half-reactions and calculate the voltage to be expected.
Iteru [2.4K]

a) 2Na(s) +2H_2O(I)→ 2Na^+(aq) + OH^-(aq)+ H_2(g)

b) 2Ag (s) +2H^(aq) → 2 Ag^+ (aq) +H_2(g)

<h3>What are half-reactions?</h3>

The half-reaction method is a way to balance redox reactions. It involves breaking the overall equation down into an oxidation part and a reduction part.

a)

2Na(s) +2H_2O(I)→ 2Na^+(aq) + OH^-(aq)+ H_2(g)

E^0 cell = E^0 (reduction)  - E^0 (oxidation)

= E^0(\frac{H_2O}{H_2}, OH^-) -E^0(Na^+/Na)

= -0.83 - (-2.71) =1.88V

b)

2Ag (s) +2H^(aq) → 2 Ag^+ (aq) +H_2(g)

E^0cell= E^0(H^+/H_2) -E^0(Ag^+/Ag)

E^0cell=-0. - (0.8) =-0.8V
