Question

Can somebody help me with this chemistry sheet? It has to do with chemical or physical reactions.

Answer 1

I just need someone to correct the answers I provided and help me figure out the ones I didn't answer (they're in red).

Answer 2

NaCl (salt) + C6H8O7 (citric acid) = ??? physical, you're only dissolving NaCl in the acid

NaCl (salt) + NaOH (sodium hydroxide) = ??? same thing

HCl (hydrogen chloride) + C6H8O7 (citric acid) = ??? same thing (2 acids don react) although citric acid might get protonated further if the conc of HCl is high enough.

NaHCO3 (baking soda) + NaOH (sodium hydroxide) = ??? Mixing a strong base (NaOH) with a species that can act as a weak base or a weak acid.

C12H22O11 (sugar) + C6H8O7 (citric acid) = ??? you will get interconversion between the types of monosaccharides (linear, cyclic), but it won't oxidize it.

C12H22O11 (sugar) + NaOH (sodium hydroxide) = ??? reduction of the carbonyl, when it's in the linear form.

C2H4O2 (vinegar) + NaOH (sodium hydroxide) =??? vinegar has some acetic acid, so its an acid-base reaction

Answer 3

@aaronq thank you so much! (:

Answer 4

no problem !
