2.) Vinegar is an aqueous solution (homogenous mixture) of acetic acid and water (aqueous="aqua"= Latin for water). To simplify the calculations let us assume that all of the acetic acid in the vinegar reacts and there is some left over "excess" baking soda. The vinegar solution is a 5% acetic acid solution. If you look at the bottle of vinegar somewhere on there it probably says "5% acidity" or similar notation. Let us estimate that about 25.0 g of vinegar...
