Limestone!
Acid, I think. It makes [some] soda-waters 'fizz' & 'treats/prevents' rust upon iron. If you knew the pH of some popular colas/sodas from a bottle or can you'd think twice before drinking them.
Ammonium bifluoride does.
It accepts the hydrogen ions released by the acid.
The pH of basic solutions will drop (become less basic) as the solution is diluted. However, if the solution contains a buffer, the pH will remain nearly constant upon dilution.

Pouring hydrochloric acid, or HCL, over a mineral will cause carbonate minerals to effervesce. This application is called the "acid test," it simply examines the mineral or rocks reaction to acid. Calcite is the most commonly found carbonate mineral and it will fizz during the acid test. Dolomite is another carbonate mineral; however, it will only fizz if it is first powdered. Experiments also show that undiluted vinegar can cause effervescing, but it produces less vivacious results. Some sedimentary rocks that fizz include chalk, coquina, oolic limestone, fossilferous limestone, and micrite. The metamorphic rock marble also fizzes.
The fizz in Coca-Cola, like all carbonated drinks, comes from dissolved carbon dioxide in the liquid. Upon opening the container, the internal pressure drops, causing the dissolved gas to escape.
Ammonium bifluoride does.
Hydrochloric acid and nitric acid have comparable degrees of acidity; the strength of either acid will depend upon the concentration.
I was searching for an answer myself and stumbled upon your question which was the same as mine. I assume that the carbon in the cigarette ash reacts with the CO2 dissolved in the beer. I do not know what chemical reaction is going on here if that is the case, hopefully someone will answer all of this with certainty for us both.
The importance of homogeneous (or heterogeneous) depends upon the application.
That depends entirely upon the application

Sulfuric acid will form calcium sulfate upon reaction with calcium.

Cells in the stomach lining ooze mucus that neutralizes acid upon contact.
