Potassium hydroxide

1. Yes flame tests are valuable for detecting ions because each metal has a unique line spectrum, which is made up of different wavelength of light that gives off a certain color when heated. 2. The reason to soak the wood splints in distilled water is because if it wasn’t done then it would be harder to receive accurate results. By soaking the wood splints it gave us time to observe the flame color without the wood getting caught on fire. 3. If the unknown mixture were a mixture of two metals then

drugs increase the smooth ER in cells, which increases the detoxification rate, which increases a person’s tolerance to a drug. Which means that a person would have to increase the dosage each time in order to get the same original effect. The increase of the smooth ER as a result of abusing a drug can lead to increased tolerance of other useful drugs, such as antibiotics. Storing calcium ions is another function of the smooth ER. These calcium ions can be used to trigger the contraction of muscle

her history of cardiac failure and hypertension and is usually given in conjunction with a potassium supplement to counteract potassium loss. Frusemide works on the body by preventing reabsorption of sodium, potassium and chloride in the proximal and distal renal tubules but mainly in the ascending limb of the loop of Henle (Tiziani, 2013, p 694). So, rather than being returned to the body the sodium, potassium and chloride are excreted in the urine and where salt

Increase in K+ ions concentration causes increase in membrane potential in crayfish muscle cell Abstract: The membrane potential of a cell is affected by ions and depends on the electrochemical gradient and the concentration gradient (Sandstorm et al, 2018). There are multiple ions that affects the membrane potential including K+, Na+ and Cl- but K+ and Na+ affect the membrane potential the most. In this experiment, we look at how K+ affects the membrane potential by changing K+ concentration

In the lab, Bunsen Burner operation, we were given 6 known substances (Calcium Chloride, Copper Chloride, Lithium Chloride, Potassium Chloride, Sodium Chloride, and Strontium Chloride) and 4 unknown substances. The goal of this lab was to match 4 of the known substances to the 4 unknown substances. Scientists are able to do this because when the wooden splint is inserted into the hottest part of the flame the electrons entered an excited state and release energy in the form of visible light. The

Introduction: The element I have chosen to research for my assignment is Chlorine. It is a very important element as Chlorine is in a lot of things that most people use in their everyday lives. Chlorine is an element of the periodic table. It’s chemical symbol is Cl, it has the atomic number of 17 and an approximate atomic mass of 35.5. It was discovered by a man named Carl Wilhelm Sceele who mistakenly thought it was a gas that contained oxygen and discovered chlorine and noticed its other

The flame test lab was to test what kind of element the substance was if it was an unknown element, or if the element was known then it would be to see the reaction that the element would have with the open flame based on its energy level. The flame test works by placing a q-tip into the water so the substance easily sticks to it and won’t come off. Then the substance is introduced to the flame by putting the q-tip over the flame and based on the colors it can be determined what kind of element it

Faith Tuma Mr. Tuckey 13/05/14 Honours Chemistry 11 Sleuth Your Slurry Abstract: This labaratory report shows that when presented with an unknown chemical substance, identification of that substance is revealed through a seires of tests that involve chemical and physical properties of that substance. Problem: You are given an unknown chemical substance that you need to be able to identify. How are you going to do this? The compound can be either harmful or toxic, so what you need

In order for the Human Body to maintain balance within its internal environment or return systems to functioning within a normal range, it must manage a multitude of highly complex interactions in order to deal with external changes that are optimal for survival. The organs that help maintain homeostasis are the liver, the kidneys, and the brain through hypothalamus, the autonomic nervous system and the endocrine system. The main function of the liver is to metabolize toxic substance as well as stabilising

out to explore the potential of modifying foods opposed to solely reducing salt intake to lower blood pressure. The best results were found in a diet consisting highly in fruits and vegetables, low-fat dairy, low salt, and high amounts of calcium, potassium and magnesium which are known to have blood pressure lowering outcomes (Mann & Truswell, 2012, pp. 336-338). Explanations for the high correlation between obesity and hypertension include an increase in volume of blood due to increased salt retention
