Alkali

content, the acidic properties and the staining effect. The ph of a solution is defined as the hydrogen ion, H+, concentration of said solution (ThoughtCo, 2017). The ph scale ranges from 0-14. Ph 7 being a neutral ph, every ph above being classed as alkali and every ph before being classed as acidic. The mouth has a neutral ph that varies slightly from 6.5-7.5. This ph is maintained by buffers in the mouth, particularly in saliva. Buffers are solutions made up of either a weak acid and its salt…

cabbage water was initially a magenta, because cabbage water is inherently slightly acidic. After the cabbage water was poured into the ammonia-water mixture the solution rapidly changed to a bottle green. With a red cabbage indicator the stronger the alkali the color the color, and the stronger the acid the warmer the color. A true neutral solution is a shade of violet. As we added vinegar pockets of bright pink flared up in the green solution. When stirred the solution’s color would be…

Element project (Br) Whats bromine? bromine (Br) is a deep red, noxious liquid, and a member of the halogen elements, or Group 17 group vlla of the periodic table. It has an atomic number of 35. What you will soon find out by my paper is how it's used in everyday life, how it's produced and its physical properties. Bromine was discovered in 1826 by the French chemist Antoine-Jérôme Balard in the residues from the manufacture of sea salt at Montpellier. He liberated the element by passing…

wear the adequate respiratory equipment. If aniline is ingested, immediately call for a medical advice and show the label or container. Avoid the contact with eyes and skin. Keep away from the incompatibles for example acids, oxidizing agents, alkalis, and metals. b) Storage: Aniline is sensitive to the light and Air. So must be stored in container that is light resistance. Containers must be kept in a well ventilated and cool area. The containers should be…

the health benefits and dangers in sodium(table salt). Also, i’m going to discuss the diseases you can get from too sodium. First, i’m going to tell you what sodium is. Sodium is a chemical element, it is a soft silver- white reactive metal of the alkali metal group; it is also the an electrolyte the body needs to regulate blood sugar. Sodium is extremely reactive, it never occurs in the free state in the Earth’s crust. The pure metal is kept under oil or kerosene because it spontaneously…

Antoine Lavoisier had published his idea on how things were categorized. He categorized them into four categories based on their chemical properties, gases, nonmetals, metals, and earths. This was very close to what it is today. Group 1 is referred to alkali metals and group 2 is referred to as the alkaline earth metals. Both of these groups are extremely reactive. Group 3-12 are referred to as transition metals. Groups 13-18 are called the main group non-metals. The metallic group of elements…

The discovery of fire has been estimated at approximately 1.7 million years ago, and can be viewed as one of the most important discoveries of mankind. However, to the humans living on earth at that time, they were highly unaware of the true scientific reasons and causes for the bright and hot flames. With scientific research, an individual is capable of breaking down the science behind fire and truly understand what is happening to an object or substance as it is burning. In order to produce a…

Colon detox In this day and age of environmental change and the effects it has on our body, it is emerging that not only does pollution and harmful toxins accumulate in our tissues and body cells but also in the integral organs of our bodies - for e.g. lungs, liver, kidneys, intestines etc. Scientists have been studying the effects of pollution in air, water, soil and the food we eat. It has been proved by scientific research that the effects of these pollutants and toxins cause long lasting…

Copper is an active metal that dissolves in alkalis. Most importantly, copper reacts with oxygen in moist air to combine with water and carbon dioxide as a chemical reaction. In addition, we can tie the properties of copper and its benefit to the coin project and how it can contribute to the project…
