In a neutralization reaction, what two products are always formed? Salt and water
Phenolphthalein in a base is __________________. Pink!
The titrant is always placed in the (buret or Erlenmeyer flask).
Predict the products and balance the equation KOH + H3PO4
Why is a standard used? A standard is a solution with a known concentration and is used in titrations so that the unknown concentration can be found.
