Calcium reacts with water. This reaction is represented by the balanced equation below. The aqueous product of this reaction can be heated to evaporate the water, leaving a white solid, Ca(OH)2(s).
Ca(s) + 2H2O(ℓ) → Ca(OH)2(aq) + H2(g)
Write the chemical name of the base produced in the reaction.*
Base your answers to questions 8 on the information below and on your knowledge of chemistry.
A company produces a colorless vinegar that is 5.0% HC2H3O2 in water. Using thymol blue as an indicator, a student titrates a 15.0-milliliter sample of the vinegar with 43.1 milliliters of a 0.30 M NaOH(aq) solution until the acid is neutralized.
Identify the negative ion in the NaOH(aq) used in this titration.*
