Acid Spills (hydrochloric or sulfuric acid): Neutralize spill with sodium bicarbonate/baking soda 2. A chemist needs 225 mL of 5.33 M HCl. Adding sodium hydroxide raises the pH: the pH has to be intermediate between that of the baking soda and NaOH. Powder form incorporates a buffer, solidifiers and color indicator (powder form ph indicator) to show when neutralizing is complete. The concentration of hydrogen ions (H +) in a solution is a chemical property referred to as pH. Spill pillows are not as messy as other absorbents, but they are more expensive. If your recipe calls for bicarbonate of soda, it is simply referring to baking soda.
