The shell that was going into the vinegar was labeled “E” (which stands for experimental) and the shell that was going to be put in the salt water was labeled “C” (which stands for control since it is the control of our experiment). Before we put them into the water/vinegar‚ we recorded some quantitative and qualitative observations such as the mass and color and shape of the shells. Then we took the two beakers and poured the 150mL of salt water or vinegar into them and labeled them according

To titrate an acetic acid solution (vinegar) with standardized 0.5M sodium hydroxide. 4. To utilize the titration results to calculate the molarity of the hydrochloric acid and the molarity and percent composition of the vinegar.

The results after being in the Dr. Pepper is the pork chop 16.1 grams‚ chicken breast 13.5 grams‚ beef roast 13.1 grams. The results of the distilled water were and vinegar were.The hypothesis which stated that the mass of the pork chop will increase was supported because the results was 16.1 grams and the chicken breast and beef roast results came out to the thirteens.

After that‚ a person my group would take the dropper and put drops of each solution on the three litmus papers and the three pH papers. There are solutions which have the property of changing their color when they come in contact with an acidic or basic environment. An example of this was vinegar‚ when it contact the litmus and the pH

This fan would then blow loose baking soda into vinegar and the two would react and expand. The expanded chemicals would then push a marble that would roll down a series of slides and into a cup on one side of a pulley. Finally‚ the weight of the marble would cause the pulley string to pull up on the door
