Weak base

The career that I want to work in when i'm older is the Navy SEALs. There is an endless list of reasons why I want to be a SEAL, But the biggest reason will be to help. I believe that everyone can make a difference in our world, I just want my Difference to be remembered for ages to come. The fact that I don't give up, and my dead eye make it all the more appealing. As a Navy SEAL you never know what to expect from waking up. SEALs dedicate their life to their craft, and team. In the SEALs you…

consider preferences; however, the overriding deciding factor was not what would make me happy; but where the Air Force needs people the most. For me, the Air Forces’ needs failed to coincide with my preferences. Both times I filled one out, I requested bases in the southeastern part of the United States. The first time they got the climate correct but the country wrong; the second time they got the country correct but the climate wrong. Damn, I would have rather walked through fire being…

Influence Matters: Becoming Who We Are “Be careful what you say and do, you never know who is watching you!” "Be careful who you look up to, you will begin to mimic their actions and attitudes!" We all have had someone say these words to us throughout our lives, but sometimes we wonder if it is true. Does influence truly have an impact on me? Is there really anyone that is watching me and looking up to me? Whether we realize it or not, influence plays a huge role in our everyday lives. Others…

Mid Fall 2012 The plane ride here was a long one. The droning engines of the C-17 went on for hours and pierced through my earplugs. I could only feel overwhelmed and excited by what was happening. I was finally getting sent overseas after four long years of basic training. A few nervous thoughts had passed my mind about what could happen, but was soon drowned out by the engines. The passenger section of the C-17 was nothing like a civilian aircraft. A few rows of seats with our gear packed in…

of a strong base with a weak acid, including its equivalence point and half-equivalence point. The following equation demonstrates the dynamic equilibrium achieved when using a weak acid: The Ka value of a weak acid can be found experimentally using a pH meter along with the concept of equivalence point when titrating an acid and a base. One half of the weak acid has been titrated at the half-equivalence point, meaning that the concentration of weak acid [HA] and its conjugate base [A—] are…

concentrations of pH atoms, they are known as bases. Electrolytes can be categorized into two groups: strong electrolytes and weak electrolytes. Strong electrolytes are soluble and completely ionize in water. Weak electrolytes do not completely dissolve and still contain entire compounds and ions in their solutions. Strong acids and bases are typically strong electrolytes, and weak acids and bases are typically weak…

children make is a response to the amount of acidity they are tasting. Acids and bases can usually be defined by your senses. For example, edible acids usually have a sour taste(4). Bases are more bitter-tasting and unstable(4). But, your senses are not the only ways you could detect acids. Sometimes you have to use measurements like the pH scale to detect if a substance is a acid or a base. Since, acids and bases surround us, it is important know information about them and how to detect…

Titrations of a strong acid or base with a weak acid or base yield results that greatly differ then a strong-strong titration. The strong-weak titrations allow for an in depth analysis of the half-equivalence point as well as buffers. The half equivalence point allows the calculation of pH from pKa, as they are both equal at the half equivalence point, proven by the Henderson Hasslbach equation. It was Henderson in 1908 that created an equation allowing for the logarithmic calculation for pH…

Aim: To use cabbage as an indicator for whether lemon juice, soft drink and antacid are acids or bases. Hypothesis: The lemon juice will be a reasonably strong acid but not so much that it can burn your tongue if consumed. The soft drink will be a weak acid, it is not as acidic as lemon and is safe to drink. I think antacid will be an acid. Theory: An indicator is used to determine the position of a substance on the pH scale. In this experiment, red cabbage is used because it contains a pigment…

homeostasis, and is controlled by the hypothalamus and pituitary gland by a buffering system. A buffer solution is used to maintain the pH at a safe acidity. “A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid” (Boundless, 2010) Equation 1 – Generic Buffer Equation HA (aq) + H2O (l) --> H3O+(aq) + A-(aq) Note that equation 1 is reversible, and all equations that are reversible have to be at a state…
