Question

Use the pull-down boxes to specify states such as (aq) or () If a box is not needed leave it blank If no reaction occurs leave all boxes blank and click on "submit Write the balanced NET IONIC equation for the reaction that occurs when hydrochloric acid and potassium nitrite are combimed Use HyO" instead of H This reaction is classified as A. Strong Acid-Strong Base B. Weak Acid - Strong Base C. Strong Acid Weak Base D. Weak Acid-Weak Base The extent of this reaction is: A. Below 50% B.50% C. Above 50% D. 100%

Explanation / Answer

HCl + KNO2

net-ionic equation,

H3O+(aq) + NO2-(aq) ---> HNO2(aq)

The reaction is classified as = A

The extent of this reaction is = A

HNO2 is a weak acid, dissociated into H3O+ and NO2- to a small extent.
