The temperature of the solution being formed in the test tube increased. A sample of the solution changed a red piece of litmus paper blue. Explain why the temperature increased (1) and why the litmus paper changed from red to blue (2) ΔΗ, Substance (kJ/mol) Na2CO3 (s) -1130.7 Na+ (aq) -240.34 CO32- (aq) -677.1Subsititute 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.
