Formic acid, HCOOH, is what causes the sting in ant bites. In the lab, an experiment calls for reacting formic acid with potassium hydroxide.   a.) Predict the products and balance the equation. Note: formic acid is similar to acetic acid, and loses the same H that acetic acid does when reacting with a base.  b.) How many grams of the salt product (ionic leftovers) is made when 55.0 g of formic acid reacts with excess potassium hydroxide?  c.) A previous scientist reported having a 96.3% yield on this reaction. How many grams of the salt product would you expect to actually collect based on that yield?

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
