Strong and Weak Acids

Don't lick, smell or touch it and you won't die.
Prepped 1M and 0.5M HCl with Mg which worked fine, but 1M sulfuric and 1M ethanoic with Bicarb doesn't seem to show any visible fizzing difference? any ideas or alternatives? maybe more dilute solutions?
 
You would need to dilute the solutions a lot in order to reduce fizzing. Bicarb is highly soluble so I would start with something like 0.1M solutions and go from there.

There is a year 7 one where they add a marble chip to 1M, 0.1M and 0.01M HCl which works quite well - you could add 0.5M as well and repeat for the other acids
