NaOH + CO 2 → Na 2 CO 3 + H 2 O. Word equation: Sodium hydroxide + Carbon dioxide → Sodium carbonate + Water. Type of Chemical Reaction: For this reaction we have a chemical reaction. Balancing Strategies: Interesting reaction and one I've never tried. Seems to be similar to bubbling Carbon dioxide through limewater, a well known chemical ...Subsititute equilibrium values and the value for Kb to solve for x. 1.7 x 10-5 = (x)(x)/(0.500 - x). We will make the assumption that since K b is so small that the value for x will be very small as well, thus the term (0.500 - x) is equal to (0.500). 1.7 x 10-5 = x 2 /(0.500) x = 2.9 x 10-3. Determine the pH of the solution.Introduction. A simple demonstration of how a precipitate is evidence of a chemical reaction taking place is performed by mixing solutions of calcium chloride and sodium carbonate to form the precipitate calcium carbonate (CaCO 3).. CaCl 2 (aq) + Na 2 CO 3 (aq) → CaCO 3 (s) + 2NaCl(aq). To Conduct Demonstration
