You may wonder about bicarbonate of soda vs. baking soda, but they are simply alternate terms for the same ingredient. For complete neutralization to take place, both excess $\ce{H+}$ and excess $\ce{OH-}$ ions need to completely react with each other, so: $$K_a\;(V_A+V_B)=\frac{(C_{Bo}V_B)^2}{C_{Ao}V_A-C_{Bo}V_B}$$. Sodium bicarbonate gets rid of 1 proton per molecule of sodium bicarb. exposed to heat source. Soda ash is also sold as "pH Up" or "pH Increaser". It only takes a minute to sign up.

In case of spills: Acid spills should be neutralized with sodium bicarbonate and then cleaned up with a paper towel or sponge. For many reasons explained in this booklet, people have become more cautious when responding to laboratory spills. A chemical spill is not a health risk if it has a low toxicity (especially if it is not volatile or a dust), is not highly corrosive, and is not a strong oxidizer. In other words, bicarbonate is considerably weaker as an acid (about 400 times) than it is as a base, so attempting to neutralize a strong basic solution with it would require an enormous amount. Lime and baking soda are two affordable and readily available chemicals that neutralize acids. A common substancethat can be used to neutralize a spilled acid is sodium bicarbonate (baking soda).
