Answer to Question #283435 in General Chemistry for nete

Question

Complete the equation of chemical reaction:

HBr + AgNO_{3 (excess)} =

Give a scheme of formed ionic micelle.

Answer 1

AgNO₃ (aq) + HBr (aq) → AgBr (s) + HNO₃ (aq)

This is an acid-base reaction (neutralization): AgNO₃ is a base, HBr is an acid.

This is a precipitation reaction: AgBr is the formed precipitate.

Reactants:

• AgNO₃ – Silver(I) nitrate, Silver nitrate Other names: Silver nitrate , Nitric acid silver(1+) salt , Lapis infernalis Nitric acid silver(I) salt , AgNO3 , Silver(I) nitrate show less
• Appearance: Colorless solid ; Odourless colourless or white crystals 
• HBr – Hydrogen bromide , Bromane Other names: Hydrobromic acid , Hydronium bromide , HBr Anhydrous hydrogen bromide , Aqueous hydrogen bromide show less
• Appearance: Colorless gas ; Colorless/faint yellow liquid ; Colourless compressed liquefied gas with pungent odour ; Colorless gas with a sharp, irritating odor. [Note: Shipped as a liquefied compressed gas. Often used in an aqueous solution.] 

Products:

• AgBr
• Names: Silver bromide , Bromargyrite , Bromyrite Silver(I) bromide , AgBr show less
• Appearance: Pale yellow solid | photosensitive 
• HNO₃ – Nitric acid Other names: Aqua fortis , Spirit of niter , Eau forte Hydrogen nitrate , Acidum nitricum , Nitric acid (> 70% in water) , Fuming nitric acid , Engravers acid , HONO2 , Red fuming nitric acid , RFNA , White fuming nitric acid (WFNA) show less
• Appearance: Colorless, yellow or red fuming liquid ; Colourless-to-yellow liquid with pungent odour ; Colorless, yellow, or red, fuming liquid with an acrid, suffocating odor. [Note: Often used in an aqueous solution. Fuming nitric acid is concentrated nitric acid that contains dissolved nitrogen dioxide
