Does the density of a liquid affect the braking of an object in free fall when it lands?

TL;DR Summary

If two objects with big diffrence in density but the same size travel through a liquid closer to the density of one of the objects, does it slow down the free fall?

In mine hypothesis I want to slow down free fall for diffrent density objects in liqudies. I have a stone wich i roughly a denisty of 2,7 g/ml and gold with 19,7 g/ml. They have the same size. Liquied glucose has the density of roughly 1,5 g/ml. In my example, I drop at the same time in a 1 meter pipe with glucose. How does the density affect the buoyancy with free fall? Does Viscosity matter in this case? Will gold fall faster?
Thank you for your help with trying to sort this out.

Welcome to PF.

It certainly seems like it will have some effect. Can you post links to the reading you have been doing so far on this question?

Also, is this question for schoolwork? Thanks.

Density is important because the driving force is due to the weight, less the buoyancy of the object in the fluid.

Viscosity is critical in that it is part of the drag equation. Terminal velocity is reached when the falling body drag balances the driving force.
