Baking Soda Vinegar Salt

This report details the observations and chemical mechanisms behind the interactions between three common household substances: Baking Soda (Sodium Bicarbonate), Vinegar (Dilute Acetic Acid), and Salt (Sodium Chloride).

A mixture of high-acidity vinegar and salt can dehydrate and kill unwanted weeds in driveway cracks. baking soda vinegar salt

Let it sit for 20 minutes, then flush with boiling water. This report details the observations and chemical mechanisms

For cleaning purposes, use dry mixtures of salt and baking soda for scrubbing, and vinegar separately for disinfecting or rinsing. Avoid combining all three in closed containers to prevent pressure buildup from gas expansion. For cleaning purposes, use dry mixtures of salt

When salt is added to vinegar, the high concentration of sodium ions ($Na^+$) and chloride ions ($Cl^-$) reduces the solubility of other gases. While this is more chemically relevant for dissolved oxygen, it can affect how gases behave in the solution. More importantly, salt dissolves readily in vinegar but has reached its saturation point in many cleaning scenarios, changing the physical properties of the fluid.

The immediate bubbling and fizzing you see is the release of CO2.
