When excess potassium hydroxide and H2SeO3 react whats the net ionic reaction for the acid-base rxn
Bad White [126]

The required net ionic equation is; 2H^+(aq) + 2OH^-(aq)-----> 2H2O(l)

The molecular reaction equation is;

H2SeO3(aq) + 2KOH(aq) -----> K2SeO3(aq) + 2H2O(l)

The complete ionic equation is;

2H^+(aq) + SeO3^2-(aq) + 2K^+(aq) + 2OH^-(aq)-----> 2K^+(aq) + SeO3^2-(aq) + 2H2O(l)

Net ionic equation;

2H^+(aq) + 2OH^-(aq)-----> 2H2O(l)

We can clearly see that this is a neutralization reaction hence water is the product of the net ionic equation.

pantera1 [17]

Answer:

sodium chloride: neutral.

tomato juice: acid.

vinegar: acid.

sea water: base.

bicarbonate of sodium​: base.

Explanation:

Hello there!

In this case, in agreement to the definition of the pH, as the measure of the acidity and basicity of a substance; it is important to recall that pH's below 7 stand for acidic substances and pH's above 7 stand for basic substances, whereas a pH of 7 defines a neutral one. In such a way, given the pH's of the given substances, 7, 4.05 to 4.65, around 2.5, about 8.1 and about 8.3 respectively for sodium chloride, tomato juice, vinegar, sea water, bicarbonate of sodium​, it is possible to assert:

sodium chloride: neutral.

tomato juice: acid.

vinegar: acid.

sea water: base.

bicarbonate of sodium​: base.

Best regards!
