Acid-Base Titration Objectives: 1. To titrate a hydrochloric acid solution of unknown concentration with standardized 0.10M sodium hydroxide. 2. To utilize the titration data to calculate the molarity of the hydrochloric acid. Materials: See handout for more info. Procedure: See handout for more info. Data and Calculations: Table 1: Volume of NaOH Required to Neutralize 10.00mL of Unknown HCl Molarity of NaOh | Trial 1 | Trial 2 | Trial 3 | Trial 4 | Initial Volume of NaOH(mL)

effects that acid rain has or does not have on seed growth and germination. The observation gathered from this experiment was that regular rain water that has a neutral pH is a better solution for seed growth. The seeds that were watered with the well water prospered more than the ones grown in the lemon juice solution. The results from this experiment were a little confusing‚ because in the first trial the seeds watered with well water germinated more than the seeds watered with the acid rain solution

Experiment 28: The reaction of Butanols with Hydrobromic Acid Pre-lab Objective: The objective of this experiment is to synthesize 1-bromobutane and 2-bromobutane with different catalyst:substrate ratios to determine which ratio is the most economically favorable. Discussion: In this experiment‚ 1-butanol or 2-butanol will be converted to the corresponding alkyl bromide with HBR‚ while using sulfuric acid as a catalyst. The sulfuric acid will accelerate the chemical reaction with being consumed

and is a strong acid. Where comparing to the conductivity of distilled water to HCL would be evidently HCL. This is because distilled water doesn’t contain ions‚ hence no movement of electrons‚ furthermore no conductivity. However since we added sodium chloride‚ distilled water will have some conductivity but no where near the amount of HCL. Comparing to the conductivity of vinegar to HCL mostly relays on how acidic each other are. Since HCL is a strong acid and vinegar is a weak acid‚ this will impact

has no effect on the percentage conversion‚ but helps to speed up reaction. Without the catalyst the reaction would be extremely slow. Stage 3: Making Sulphuric Acid In principle‚ you can react sulphur trioxide with water to make sulphuric acid. In practice‚ this produces an uncontrollable fog of concentrated sulphuric acid. Instead‚ the sulphur trioxide is absorbed in concentrated sulphuric acid to give

Acids and Bases Mirza Hasan Mammadov Acids and bases are really important in our daily day life. So let’s start with telling the definitions of them. Starting with acids‚ they are a substance which dissociates in water in order to produce one or more hydrogen ions. Also we can write H+ instead of hydrogen ion. Bases have the same definition‚ although the difference is that it firm hydroxide ions instead of hydrogen ions. We can write OH- instead of hydroxide ion. All alkali is bases but not

ACID ATTACKS UNDER IPC : AN ANALYSIS INTRODUCTION Acid attacks are a form of violence against women‚ where the perpetrator splashes a person or object with acid in order to deface or kill them. Although acid throwing‚ also known as vitriol age‚ has been a form of violence known to be committed throughout history‚ there has been a steep rise in the cases documented in recent years‚ particularly in certain South Asian countries. Some of this increase has been attributed to better documentation

Lloyd Term 2‚ 2014 Lauric Acid Experiment Teacher: Mr Oliver Contents 1.0 Introduction Elements and the compounds can exist in distinctive physical states. Liquid‚ solid‚ gas and plasma. Every element and compound has a distinctive melting and boiling point. When a substance reaches its melting and boiling point it will change phase. For example the molecules in a solid being heated gain energy and eventually are able to not only vibrate but
