Military base

matrix was constructed. The pH of each solution was measured and labeled from a strong base to a very strong acid. Then, react one of the unknown solution with all of the others and note any visible reaction (change in color or formation of precipitate) that occurs. After that, some the solutions might be identified throughout the…

The Case of the Mix-Matched Chemicals Hypothesis: By measuring the pH of the unknown and known chemicals, the types of chemicals in the unknown bottles will become known. Purpose: The purpose of this experiment is to determine the type of chemicals that are inside the mislabeled bottles. Materials: • pH strips • 8 bottles of known chemicals: o silver nitrate o iron (III) nitrate o copper (II) nitrate o sodium iodine o sodium hydroxide o nitric acid o lead (II) nitrate o sodium…

fish muscle differed depending on the season. g/100 g fish muscle Chemical constituents 77.30 ± 0.53 Moisture 18.85 ± 0.34 Crude protein 2.50 ± 0.29 Total lipid 1.51 ± 0.61 Ash Table (1): Proximate chemical composition of sea bass fillets (on wet bases). Values are mean ± standard error from triplicate determinations. They also reported that there is an inverse relationship between moisture and…

basic. For instance, a pH of two is going to be an acidic liquid. Thus, a pH of twelve would be measured as a basic liquid. Additionally, a strip of litmus paper will demonstrate that a solution contains an acid. However, if the solution contains a base the paper will turn blue, and if it turns red the solution is an acid. Also, like the litmus paper, Multip-pH is a paper impregnated with an indicator solution. The paper is dipped in the solution and is matched with a pH color chart.…

Assessment Directions: Choose the correct answer from the choices below. 1. The mass of an atom expressed relative to the mass of? A. Carbon-6 C. Carbon-12 B. Carbon-10 D. Carbon 2. It is defined as the number of atoms of that element equal to 12.0 grams of an isotope of Carbon. A. Molar Mass C. Particles B. Stoichiometry D. Mole 3. The first step in every Stoichiometry Problems is to? A. Balance the equation C. Solve the mass of the…

PH levels are a measure of how acidic or basic your beverage is. They show what beverages are more acidic, like soda, and what beverages are more basic, like water. It’s measured on a scale from one to fourteen. One through six are the acid levels, seven is the only neutral level, and eight through fourteen are the basic levels. First, get 2 drinks of choice and pour them into two different cups. Then, record its pH level, as well as the room temperature. Next, take another liquid and mix it…

there is an unknown solution (analyte), titrant is used for identifying the concentration of that unknown by adding titrant to analyte. (using burette) Acid –base indicator: acid- base indicator is an indicator that determines the pH of a solution by changing its color due to H+ ion concentrations inside the solution. Indicator range: acid- base indicators change their colors when pH changes. However, they are useful in a specific pH interval. pH of a solution cannot be determined if pH is out…

According to Jefferson (2011), “Liquids with Carbonization have a faster effect to dissolve an aspirin than many other liquids that don’t have carbonization.” In this experiment, I am testing which of the following liquids Sprite,Coke,7-Up,Fanta,Ginger Ale,Water,Lemonade, Club Soda, or Orange Juice will dissolve a coated aspirin and an uncoated aspirin the quickest to result in the fastest relief possible. There are many things that may affect the results such as pH level and if a drink that is…

Vinegar Dilute and Impure Acetic Acid or better known as vinegar is a compound formed by the chemical reaction of carbon, hydrogen and oxygen. The composition of vinegar is acetic acid (C2H4O2) and water. Also, the formula for this compound is CH3COOH. These elements are nonmetals,so the type of bond that this substance made is covalent. Vinegar has many kind of properties and utilization in several ways. For example, it can be use for food preparation, cleaning and health. When added in…

After thymol blue was added, the pH-buffered samples developed the colors of red, yellow, green, and blue as the pH of the solutions increased (Figure 3.1A). The pH-2 buffer turned to a light red-pink color, while pH-3 to pH-6 displayed very similar forms of rich yellow or light orange (Figure 3.1A). The neutral pH buffer solution appeared as a saffron green colored solution (Figure 3.1A). A mixture of yellow and green was apparent in the dijon color of the pH-8 buffer (Figure 3.1A). The buffer…
