For this experiment, I wanted to make sure that I used a variety of substances so that I would have a range of pH levels as an outcome from the exercise. From this, I was surprised about the outcomes of several household items pH levels. For example, I was surprised about how three of the substances I tested came back with around the same pH level of 4: cranberry cocktail, lemon juice, and soy sauce. One reason I was surprised that these 3 substances had the same pH level was because I was expecting the lemon juice to have a lower pH level, around 2, instead of a 4. This is because in the acid base property notes from class, there is a picture that labels lemon juice at a pH level of 2. Therefore, the lemon juice I used was most likely diluted

This explains why the pH level of the lemon juice I tested was 4, which is higher than what was anticipated, 2. Another outcome I was surprised about was that honey had a low pH level of …show more content…
Therefore, I learned that a substance does not necessarily have to taste sour in order to have a low pH. Also, from the experiment I was surprised about how the hand sanitizers pH level was 6, making it an acid. This was startling because in the acid base property notes, it states that cleaning products are classified as bases. Although hand sanitizer is not a household cleaning product, it does help reduce the number of germs on your hands, which is similar to how a household disinfectant reduces the number of germs on a surface. Therefore, I was surprised that the hand sanitizer did not receive a pH greater than 7, which would make it a base, because its job is similar to what a household cleaners job is. Through this experiment, several substances denied their set characteristics for what makes an acid or base. Therefore, these unique substances caused me to want to learn more about how common it is for a substance to deny the assigned characteristics of an acid or base. This is because even though I simply tested just 10 household items, 2 substances came back with a unexpected pH level which could not necessarily be explained through diluting the substance with water, like the lemon
