When carbon dioxide is bubbled through limewater, a precipitate forms. Concepts ... The pH range of the bromthymol blue indicator is 6.0–7.6 with the color change of yellow (pH 6.0 and below) to blue (pH 7.6 and higher). The pH of limewater is 12.4 so the solution is initially blue.
WebFeb 2, 2024 · The net reaction of CaF 2 with strong acid is thus. CaF2 ( s) + 2H + (aq) → Ca2 + (aq) + 2HF(aq) Example 18.7.1 shows how to calculate the solubility effect of adding a strong acid to a solution of a sparingly soluble salt. Sparingly soluble salts derived from weak acids tend to be more soluble in an acidic solution. WebThe concentration of Ca 2+ in a saturated solution of CaF 2 is 2.15 × 10 –4 M. What is the solubility product of fluorite? Solution According to the stoichiometry of the dissolution equation, the fluoride ion molarity of a CaF 2 solution is equal to twice its calcium ion molarity: [F −] = (2molF − /1molCa2 +) = (2)(2.15 × 10 − 4M) = 4.30 × 10 − 4M
Limewater is the common name for a saturated aqueous solution of calcium hydroxide. Calcium hydroxide, Ca(OH)2, is sparsely soluble at room temperature in water (1.5 g/L at 25 °C ). "Pure" (i.e. less than or fully saturated) limewater is clear and colorless, with a slight earthy smell and an astringent/bitter taste. It is basic in nature with a pH of 12.4.
