I'm just wondering, why does H2SO4, and HNO3 diffuse into agar jelly cubes faster than HCl? It makes sense to me that the acids diffuse faster into a 10mm3 cube than a 30mm3 cube, but why does the type of acid make it happen faster?

The difference in diffusion rates between H2SO4, HNO3, and HCl is mainly due to their molecular size and polarity. H2SO4 and HNO3 are stronger acids with larger, more complex molecules compared to HCl, which makes them more efficient at breaking through the agar matrix. Also, their higher charge density can lead to faster interaction with the agar, allowing quicker diffusion.
