In banana bread, baking soda does more than just help the loaf cake rise: What does baking soda do in banana bread? It's a complete leavening agent and all you have to do is wet it and apply a little heat to make it react. The acidity in banana bread could come from the mashed bananas, which have a pH that is between 4 and 5.īaking powder is made from sodium bicarbonate, acid(s), and a drying agent (or anti-caking agent) like cornstarch. Remember that baking soda is sodium bicarbonate and requires acidic ingredients to react to form carbon dioxide. Baking powder wasn't the reliable chemical leavener it is today.

If you add washing up liquid ( dish soap ) to your eruption mix the bubbles make the washing up liquid bubble up, giving the appearance of lava erupting from a volcano. The reaction releases carbon dioxide gas, which is the bubbles you see. Vinegar is an acid and bicarbonate of soda is an alkali. If you combine an acid and an alkali they react together to neutralise each other.

Baking soda volcanoes and coke floats were our favourite summer activities. I remember making one with my little brother in the kitchen when he was about 4 or 5. When you think of great science experiments for kids one of the first that springs to mind is probably a baking soda volcano and vinegar volcano.
