n Experiment 14, a Clock Reaction was set up by combining the following reagents in a 250 mL flask. KI(aq) [0.2 M], 10.0 mL Starch [1%], 0.6 mL Na2S2O3(aq) [0.40 M], 0.40 mL KNO3(aq) [0.20 M], 19.0 mL EDTA(aq) [0.10 M], 1 drop The reaction began when 10.0 mL of (NH4)2S2O8 (aq) [0.20 M], ammonium peroxydisulfate, was added to the flask and it took 262 s for the solution to turn dark blue. If the student set up the same reaction in a new flask, but used 0.8 mL of Na2S2O3(aq), approximately how long would it take for the solution to turn blue

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.
