In baking, cream of tartar is used as a leavening agent, and to increase the volume of egg foam. What necessary gas is produced when cream of tartar is combined with baking soda?
Answer Carbon Dioxide
Believe it or not, cream of tartar is technically an acid and a byproduct of wine production! Similar to yeast, it's used as a leavening agent as it reacts with baking soda to create buoyant carbon dioxide.
