Pickling is the process of preserving food by anaerobic fermentation in brine or vinegar. The resulting food is called a pickle. This procedure gives the food a salty or sour taste. In South Asia‚ edible oils are used as the pickling medium with vinegar.[1] Another distinguishing characteristic is a pH less than 4.6‚[2] which is sufficient to kill most bacteria. Pickling can preserve perishable foods for months. Antimicrobial herbs and spices‚ such as mustard seed‚ garlic‚ cinnamon or cloves‚ are

also releases gases. An exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice and baking soda‚ammonia and vinegar‚ and finally‚ hydrochloric acid and sodium hydroxide. I did each experiment when the acid was 0‚ 20‚ 40‚ 60‚ and 80;all in degrees Celsius. Therefore‚ I could compare the exothermic reaction with the endothermic reaction at each temperature.

Title: The Effects of Microwaved Water on Plant Growth Problems: 1. What are the factors that make the microwave harmful? 2. What happens to the water (when microwaved) that causes it to affect plant growth? 3. What are the effects of microwaved water on the growth of plants? Hypotheses: 1. The micro wavelength radiation the microwave contains makes it harmful. 2. The water undergoes ionizing radiation which causes it to affect the growth of the plant 3. The growth of the plant

In this experiment‚ we will be finding out what happens to gummy bears when put in different solutions to observe and predict why they dissolve‚ shrink‚ or grow in each of them. The solutions that we are using are 2 % Low-Fat milk‚ apple cider vinegar‚ filtered water‚ sugar‚ baking powder‚ and salt. The prediction is that when the gummy bears are in baking powder‚ they will be hypotonic‚ but will be hypertonic in sugar. Our controls are the same intervals of time and the same type of gummy bear

The Incredible Egg Procedure: On October 5‚ I gathered a large Styrofoam cup‚ an egg‚ some vinegar‚ some corn syrup‚ and some water. Before I started the lab‚ I weighed the egg on a scale. Because the egg would just roll off the scale if I set it down by itself‚ I weighed the cup‚ and then added the egg. After I knew how much the egg weighed‚ I poured enough vinegar in the cup to submerge the egg. I then covered the top of the cup with plastic wrap and set the egg aside. The next day‚ I washed

Question: Why would sensing and responding to vinegar be important to an organism? -It could train them to respond to certain smells and respond in a certain way. How would natural selection affect an organism’s ability to sense and respond to this stimulus? -The organism depends on its ability to sense and respond. The organisms could compete for water or hydration. What other types of stimuli would be important for the organism to respond to? - An organism that is used to light is

The first step was to prepare 400 mL of an 0.1 M solution of NaOH. This was done by diluting from the 6 M solution that was provided. Next‚ 0.715g of KHP was weighed using the glazed paper and the triple beam balance. The KHP was then transferred to the 250 mL Erlenmeyer flask. Using a graduated cylinder‚ 50 mL of deionized water was measured and added to the flask. The KHP was dissolved in the water‚ and few drops of phenolphthalein were added. Moreover‚ the burette was rinsed with deionized water
