  • We use Phenolphthalein, a tracer that will turn pink when pH more than 7 and invisible when pH less than 7

    At first, there is water so pH = 7, invisible
    Then we add Ca(s), which turns the next reaction:
    Ca(s) + H2O — Ca(OH) + H2

    Since there are lower concentration of H+ expect basic solution
    pH is more than 7 so it is pink
    Then we add vinegar

    CH3COOH + Ca(OH)2 —- Ca + and CH3COO- and H2O
    this is neutralization, pH = 7 but this is hard to get, there is always extra acetic acid (from vinegar) so…

    There is excess of CH3COOH
    CH3COOH == CH3COO- and H+

    High concentration of H+, this is acidic
    pH is less than 7 so it is now invisible

    Then we add NaOH:
    NaOH + CH3COOH = Na+ and CH3COO- and H2O

    Since NaOH is in excess:
    NaOH is basic
    pH is more than 7, expec pink color
