Acid-base titrations are used to calculate properties of an acid or a base by titrating them with a strong Acid or base. In a titration, certain amount of volume of one substance usually a strong acid or base, a titrant, is added to another substance, an acid or base of some kind, until a change in properties are observed. Strong acids and bases are used because they allow the neutralization reaction between the acid and base into salt to go to completion. By titrating an unknown concentration of acid or base with a known concentration of acid or base, you can calculate properties such as the concentration and pKa of the analyte.
During the standardization part of this reaction, we are adding Sodium Hydroxide, NaOH to a solution…
The concentration of phytic acid was determined spectrophotometrically in three tested plant materials of Gishta as shown in table 2. The concentrations of phytic acid were obtained from 5 g dried leafy material. All the leaf samples contained phytic acid (detection limit 0.025 mg/ml) in this study. This may have been due to the fact that there was a limitation in terms of the detection concentration since concentrations less than mg was not tested. Seed extracts was found…
and for you to get rid of bad breathe, white spots, and even tooth decay, follow this method for a minimum of twice a week.
7. Baking soda with strawberry. Baking soda is a natural teeth whitening agent and strawberry has a vitamin c content that helps in removing white spots on teeth. Strawberry also removes cavities and other stains in your teeth. You need to mix 2 tablespoons of baking soda and 3 fresh flashes of ripe strawberry pulps to make it into a fine paste. Wet your brush and dip it…
The “Acid Bath Murderer” case was about a man named John George Haigh. It was said that he killed his boss and dumped him into a forty-gallon barrel of acid (Casale,2017). Like most known killers, Haigh blended well into society. Born into a strictly religious family on July 24, 1909, Haigh claimed his childhood to be strict and somewhat lonely. During his youth, Haigh had an accident which resulted in having a blue bruise on his head. His mother told him that this blemish was a result of his…

The Separation of Three Organic Compounds by Acid-Base Reactions and Liquid-Liquid Extractions
The purpose of the experiment was to isolate the three mixtures 9-fluorenone , benzoic acid and benzocaine by the liquid-liquid extraction method and the acid-base reaction technique. Using the acid-base reaction technique, the acid and base are neutralized, producing salt and water. By using the liquid-liquid extraction method, two…
Acid rain is any form of precipitation that is extremely acidic, causing harmful effects on the environment. The unusual acidity of acid rain is caused by the high levels of nitric and sulfuric acids in the atmosphere, generated mostly by human activities but also by natural activities. This document will describe the process of acid rain from creation to the effects it has on the environment.
In the formation of acid rain, natural and human-made sources are known to play a…
Plastics have played a major role in shaping modern society, ultimately improving the quality of life. Making up most things man-made, plastics surround us every day. They possess unique characteristics; plastics can be tough and rigid yet still flexible and can be opaque yet transparent. The building blocks of plastics are small organic molecules often known as monomers, which then join to other monomers creating long molecule chains called polymers in a process called…
ANTACID ANALYSIS: DETERMINATION OF STOMACH ACID NEUTRALIZATION USING ANTACIDS
Authors: Alexxis Harris
Affiliation: Department of Chemistry, University of Central Florida
The purpose of this experiment is to identify which antacid is the best at neutralizing stomach acid. Antacids are commonly used self-prescribed medications. The stomach produces hydrochloric…
Company manufactures the sulphamic acid. During the process scrubber through SO3 gas liberate the atmosphere. So these SO3 undesirable gases are reducing. The SO3 gas is hazards and it is pollute the atmosphere. In this project we can solve the possible solution then apply to the plant scale.
1.2 Objective Of Projects
In these manufacturing process of sulphamic acid first raw material put at the batch reactor and after some time hot discharge solution in put the dumping…
3. SAFETY AND ENVIRONMENTAL ASPECTS OF SULPHURIC ACID PRODUCTION
1. Safety Aspects
1. Basic Safety Aspects due to Physical properties and behaviour of Sulfuric acid.
Basically, we know attention is paramount when adding water to a highly concentrated acid and this is the case with sulphuric acid which is highly risky. Sulfuric acid can have serious adverse effects like burns if it contacts the skin. This is due to the dehydrating properties of the acid on organic materials. Also, when the…
