Acid rain is rain that has become acidic‚ because of air pollutants in the atmosphere. Rain has a normal pH level of around 5-5.5 which is only slightly acidic. 7 on the pH scale is the neutral and anything below that is considered acidic. Acid rain has a pH level around 4 which is 10 times more acidic. Acid rain can fall in many different ways and has many effects on the environment. Acid rain is caused by air pollutants in the atmosphere. These air pollutants are mainly from man made resources

Carboxylic Acids and Their Derivatives Ma. Marielle M. Medura Prof. Emma Boncales Chem 23A (TTH 01:00-4:00 p.m) Carboxylic Acids and Their Derivatives I. Introduction Carboxylic acids is an organic compound that contains a carboxylic group(-COOH). Its general formula is R-C=OOH with R referring to the rest of the molecule such as H and C. They are directly attached to a carbonyl group and the interaction between them affects the reactions of each. The polarity of the O-H bond

one of two very similar pentose rings. Ribonucleic acids contain the sugar ribose. Deoxyribonucleic acids contain the sugar deoxyribose. The only difference between these two sugars is that deoxyribose contains one oxygen atom less than ribose. Pentose sugars are essential because they are involved in linking different nucleotides together by condensation reactions. The Nitrogen-Containing Bases There are two types of bases found in nucleic acids. The purine bases have two nitrogen containing rings

ICSE Class X Chapter 5 Hydrogen Chloride and Hydrochloric Acid Hydrogen chloride (HCl) : Formula : HCl Nature : Covalent. Molecular Mass : 36·5u [i.e. HCl = 1 + 35·5 = 36·5] Occurrence : (i) Present in gastric juices. (ii) Present in volcanic gases. Laboratory preparation of HCl gas : Hydrogen chloride gas is prepared in laboratory by heating conc. H2SO4 with NaCl. NaCl + H2SO4 Heat → NaCl + NaHSO4 Heat → NaHSO4 + HCl Sodium hydrogen sulphate Na2SO4 + HCl

Question: Effects of pH on amylase activity Introduction: Amylase is an enzyme that is in human’s saliva as well as the pancreas. Enzymes are biological catalysts that speed up a chemical reaction. They break down complex molecules into simple ones. In this case‚ amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example‚ may taste sweet to us‚ because they contain starch. The optimum pH for pancreatic amylase is the pH of 7. In the experiment

ACID BASE IMBALENCE INTRODUCTION The body normally maintains a steady balance between acids‚ produced during metabolism and bases that neutralize and promote the excretion of the acids.Many health problems may lead to acid base imbalance.Patients with Diabetis mellitus ‚COPD‚and kidney disease frequently frequently develop acid base imbalences. Vomiting and diarrhea may also cause acid base imbalance.The kidneys are an essential buffer system for

are several purposes to the amino acid lab experiment. One reason is to help us understand the concept of acids and bases and how they interact with one another. Another purpose is to understand what occurs when placed with the existence of buffers. Lastly‚ the experiment is to help us understand the applications of titrations and how it can be used in a real world setting‚ in this case‚ the identification of an amino acid. One must understand that amino acids all have special characteristics

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
