Which One Dissolves Faster?

Question; If I change the type of liquid I put Alka- Seltzer in how will the liquid type affect the reaction time?

Background; The experiment I'm testing is a chemical reaction. A chemical reaction is when the chemicals in an object change. when chemical reactions happen the outside appearance doesn't have to for something to be a chemical reaction.Some signs of a chemical reaction is color change, production of light, change in temperature, formation of a precipitant. In a chemical reaction the part the reactions and the product. The reactions are 2 or more substances that are mixed together to make the product. The product is the outcome of the reactions being mixed together. Some examples of a chemical reaction is baking a cake another one is making coffee which is both a chemical and physical reaction. I will test chemical reactions by putting Alka-Seltzer witch when put in liquid has the chemical reactions are effervescent(gets bubbly) and solvent (It dissolves) into water, Coke Zero and Orange juice. A solution by definition is "a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent)." Meaning that a solution is two or more things mixing together. In this experiment i plan to use coke zero witch has carbonation and orange juice that is acidic. 

HYPOTHESIS;My hypothesis is that if I put Alka-Seltzer in water, Coke zero and, orange juice. The fastest time for the chemical reactions to take place will be in the coke zero and the longest will be in the orange juice.I believe this because coke zero has carbonation and id already fizzy so it will work cohesively and be done faster but, orange juice has acidic im not 100 percent sure how acidic works but i believe the acidic will slow done the process.]]> 2019-02-06 19:20:24 UTC https://padlet.com/s_porter1/6x8juezhwi5e/wish/328450557 s_porter1 https://padlet.com/s_porter1/6x8juezhwi5e/wish/328451264 Materials; Alka-Seltzer, Orange Juice, Coke Zero, Water
Procedures;
1.) Get your materials, diet coke, water, orange juice, a timer and alka-seltzer.
2.) Put your measure out your water to a half cup.
3.) Put the 1/2 cup into a cup
4.) Open the alka seltzer 
5.) Get the timer readdy 
6.) Drop alka seltzer into cup of water and start timer
7.) Stop the timer when all bubbles disappear 
8.) Wash your cup out and write down the time
9.) Repeat steps 1-8 for control
10.)Repeat steps 1-8 but this time have coke zero in the cup not water 
11.)Repeat steps 1-8 but this time use orange juice not water or coke zero 
12.)Put your materials away and clean up your area

Written Observations;  
DIET COKE 
Trial One: when i poured the "Alka Seltzer" into the cup it stared fizzing up and there was lots of bubbles. 
Trial two: the same as last time just longer
Trial three: Felt like there was more bubbles than the last two and, went on a little longer. 

OJ
trial one; lots more foam and less bubbles than diet coke also goes on waaaay longer.
trial two; the same as trial one maybe a little less foam and more bubbles, painfully long time for all bubbles to go away.
trial three; shorter a little more foam then trial one and, two the foam almost went out of the cup. Waaay less bubbles too a bit shorter than trial 1+2.

WATER
TRial one: so much shorter than oj and diet coke. more bubbles + foam then D.C(diet coke) but less than oj. shorter than both D.C and oj.
TRial Two; same as last time shorter reaction time though
Trial three; same as trials 1+2

I did 1/2 a cup of each liquid and, i put a whole piecot in each one half cup of liquid. The result were that water had the lowest time at an average 1:39 Diet coke had a average of 2:07, O.J average of 2:35, FRom the numbers i understand that because the oj was acidic it probably played a part and the carbonation didn't speed up the time. IN the end my hypothesis only was 1/2 right, the oj made for the longest reaction time but water was the fastest. The diet coke was not the fastest the water may have worked faster because it was meant for it or because the soda was diet. Some faults may have been that the diet coke did fizz up in the bottle, the oj wasn't plain oj it was mango orange juice, the alka seltzer was really picot and it was able to be poured out. THis can help the real world when making a cake because you want the bake time to be even shorter. You could test if carbonation makes this dissolve faster.
