The ability of a liquid to hold a static charge is primarily influenced by its resistance. Resistance in this context refers to how well the liquid prevents the flow of electric charge. Materials with higher resistance do not allow charges to move freely, which means they can accumulate a static charge more easily.

In general, substances that are good insulators, exhibiting high resistance, are better at holding static charges because they prevent charge dissipation. Conversely, liquids with low resistance, such as conductive electrolytes, allow charges to move and thus cannot effectively store static electricity.

The other characteristics mentioned—conductivity, viscosity, and density—are relevant to the behavior of liquids but do not have the same direct relationship with static charge retention. Conductivity directly relates to how easily charges can flow in a material, viscosity pertains to the thickness or flow resistance of a liquid, and density refers to mass per unit volume, none of which primarily determine a liquid's ability to hold static charge like resistance does.
