Chemical Raising Agents Bread Soda Baking Powder Equation to show how Chemical Raising Agents Work!!!! Alkali + Acid = Carbon Dioxide

HOW CARBON DIOXIDE WORKS??? HEAT

2. Bread Soda Bread soda is alkali When mixed with buttermilk (acid) and a liquid it makes CARBON DIOXIDE The CARBON DIOXIDE expands and rises when heated, raising the dough

3. Baking Powder Baking powder is a mixture of bread soda and an acid When moistened by eggs or milk CARBON DIOXIDE is produced The CARBON DIOXIDE expands and rises when heated, raising the dough

4. Yeast Yeast is a micro organism It produces CARBON DIOXIDE in the dough The CARBON DIOXIDE expands and rises when heated, raising the dough Used in commercial breads
