Acid

determine the molarity of an unknown acid. Moreover, acids and bases react with the known stoichiometric ratios based on the coefficients of the balanced chemical reactions. If the stoichiometric ratio of an acid-base reaction is known the unknown concentration can be determined, however the reaction must have gone through completion and the number of moles of one of the components needs to known. The pH scale can be used to determine the change in concentration of an acid or base. The pH scale is calculated

that a strong acid that is titrated with a strong base will produce a resultant solution has a pH that is slightly over 7. This is because strong acids have a lower pH and solutions that are less basic than weak acids that have been titrated with strong bases. When a weak acid is titrated with a strong base it will produce a resultant solution that is well above 7 because it starts off with a higher pH. Acids and bases with high concentrations result in large changes in pH, while acids and bases with

concentration of NaOH was used to identify the unknown acids, this value is shown is experiment 16.1. This mean standardized concentration was 0.0784 M. By titrating a known amount and concentration of this standardized base to the unknown acid, a titration curve and its derivative could be plotted in order to find the molar mass and acid dissociation constant. The first unknown acid titrated, BGYW, was identified to be Maleic acid, C4H4O4. The identity of the acid was found by taking both the molar mass and

Patterns: The lower a metal is in its group the faster the reaction it will have with water. This is true for both group 1 and group 2. The metals reacted to form Hydrogen gas and a solution that was alkaline. When going down a group the Electronegativity decreases which results in the element losing their valence electrons easier, making them react more quickly. The group 1 elements had similarities in their appearances, Potassium and Lithium were in a cylinder shape, but sodium was white and had

(a) When dry pH paper was placed over household ammonia, the paper quickly turned a dark blue, indicating that it was a base. (b) When moist pH paper was placed over household ammonia, the paper turned dark blue faster than when dry, still indicating that it was a base. (c) When pH paper was placed over bleach, the paper turned blue, which indicated that it was a base. (d) When pH paper was over ammonium carbonate, the paper turned dark blue even faster than the moist paper over household ammonia

In the lab experiment called Acids and bases; the lab was design for participant to figure out whether certain household chemicals are acids or base and what color they can turn in to when being added to cabbage juice. An acid are a solution that has lose hydrogen ions that usually taste sour. However, some household solutions are acids such as vinegar and citrus fruit juices. Bases are solution that pull hydrogen ions out of solution and into themselves and it usually feels slippery. In this experiment

The purpose of this experiment was to test acid-base solutions to determine the absorbance intake they had do to their different pH levels. To do this, four similar samples were recorded with a different amount of NaOH added to each one, which would change the pH level from acidic to basic. Acidic solutions take in less absorbance, while basic solutions will have the most absorbance, as well as higher Ka and pKa values. The acidic solutions would have negative absorbance from 100% or higher transmittance

Acid-Base Imbalance Janet J Memoli Grand Canyon University NUR 641E September 30, 2015 Acid- Base Imbalance One of the basic concepts that new nurses need to learn is that homeostasis in the body is maintained by the acid base balance in the body. That concept is critical when looking at arterial blood gases. This can help guide the nurse to anticipate what the doctor will order and the education that she needs to give the patient and the family. This case study should help to illustrate

Acid Rain Acid rain is polluted rain. The pollutants go up to the atmosphere and when it rains it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain, snow, hail, or even fog. The scientific term for acid rain is acid deposition which means when the acid is taken from the air and is deposited on the earth. Major industries, coal burning factories, power plants and automoble engines

Acid can take the form of clouds, fog, rain, snow, hail, mist, and dust particles. Acid precipitation, such as rain, looks like normal rain and tastes like it as well. In small amounts, it is harmless. In other ways, it is anything but. Acid precipitation does not affect people directly, but when it is inhaled, it can cause heart problems and affect the lungs, giving people asthma and bronchitis. Some of the effects that acid precipitation has, is that it has the ability to lower the natural pH
