Nahco3 And Ch3cooh Reaction Lab

Reactants Predictions Before
Combining Observations After
Combinin g
Starch + I2 No reaction, starch will remain white Reaction; black deposits on the glass tube. Starch turns black
Food coloring + NaOCl No reaction; will turn lighter Reaction; the solution that was dark blue turned into light blue
Food coloring + CH3COOH No reaction; color will turn lighter No reaction; when both combined, the color (dark blue) remained the same
Food coloring + NaOCl
+ CH3COOH No reaction; solution will remain blue Reaction; solution turns light gray
Red cabbage + NH3 No reaction; solution will remain purple Reaction; solution turns into yellow green
Red cabbage + CH3COOH No reaction; solution will remain purple Reaction; solution turns pink
NaHCO3 + NH3 I predict that NaHCO3 combined with NH3 will bubble as a reaction. The NaHCO3 seems to be settled at the bottom and NH3 is on top.
The baking soda is still at the bottom
Na2CO3 + CH3COOH No reaction; washing soda will sink Reaction; release gas (bubbles) because of washing soda

MgSO4 + CH3COOH No reaction; the liquid will remain clear No reaction; the combined solution was clear
MgSO4 + NH3 No reaction; liquid will remain clear Reaction; liquid is partially cloudy
MgSO4 + Na2CO3 I predict nothing will happen when MgSO4 is combined with Na2CO3 Nothing happened.
