NaNO3 is neutral solution PH = 7 because of it is salt of strong acid(HNO3) and strong base (NaOH)
NaNO3 solution PH = 7
Na2CO3 solution is basic nature PH >7 because of it is salt of weak acid (H2CO3) and strong base ( NaOH)
Na2Co3 solution PH is greater than 7
NH4Cl solution is acidic nature. PH<7 because of it is salt of strong acid (HCl) and weak base ( NH3)
NH4Cl solution PH is less than 7
NaHSO4 is neutral solution PH = 7 because of it is salt of strong acid(H2SO4) and strong base (NaOH)
NaHSO4 solution PH = 7
Na2SO4 is neutral solution PH = 7 because of it is salt of strong acid(H2SO4) and strong base (NaOH)
Na2SO4 solution PH = 7

5. Which of the following statements applies to the E2 mechanism? a) It occurs with inversion of stereochemistry. b) It occurs with racemization of stereochemistry. c) It proceeds through the more stable carbocation intermediate. d) The C-H and C-X bonds that break must be anti. e) Use of a bulky base gives the more highly substituted alkene product.
14. A solution which contains only one of the following cations: Ag+, Pb2+, or Cut is tested with various reagents and the following results are obtained: Reagent Result 0.2M NaCl Precipitate 0.2 M Na2SO4 No Precipitate 0.2 M NaNO3 No precipitate a) Which cation does the solution contain? b) Explain why each of the other two ions is not the ion in the solution.
Why it's c ? Explain with show work
