What we need to know is that every oil has a specific index for strength, cleaning, etc.
All of them are determined by the amount of certain fatty acid in the oil.

When we make soap, what we need to know is that oil has a special role to play in that soap.

A common antacid contains the acid-neutralizing agent sodium hydrogen carbonate. Write the chemical formula for sodium hydrogen

kaheart [24]

Sodium hydrogen carbonate has:
$sodium \: ion ( {Na}^{+}), hydrogen \\ ion ( {H}^{+}), and \: carbonate \\ ion ( {CO3}^{2-})$
The + from Na+ and + from H+ makes 2+, and therefore the 2- from CO3 evens the charges to neutral.

Not to be confused with Sodium Carbonate, (Na2CO3), which lack an H, Sodium Hydrogen Carbonate is sometimes shortened to just Sodium Bicarbonate. It is used in the kitchen (cooking) as "baking soda."

Formula: NaHCO3
