you observe it‚ only one phase is visible. (1 mark lost) 43. Sodium Carbonate will be very soluble in water because of the positive ions of sodium attached to the negative ions of the carbonate. Methanol will be partly soluble in water due to it’s small size and the presence of the OH group in the molecule and it’s very polar nature. Gasoline (Octane)‚ is completely insoluble since it is non-polar.

Preparation of Sodium Chloride through titration Abstract: acid-base titration is a technique commonly used to determine the moles of acid in a sample by adding a known volume of strong base of a known concentration. The strong base provides the hydroxide ion‚ to react quantitatively with the acid. The point at which the acid is completely and exactly consumed the known quantity of base is called the equivalence end point and is signalled by a colour change in the solution (end point). This colour

IF YOUR BACK HURTS‚ DON’T IGNORE THE PAIN. PHYSIOTHERAPISTS WILL CORRECTLY ASSESS THE PROBLEM AND PROVIDE SAFE & EFFECTIVE TREATMENT. Roughly 70 to 85 percent of people have experienced back pain at some point in their lives. Many cases of lower back pain are the result of a muscle strain. The good news is that such back pain generally heals quickly in a few weeks or months. Depending on the causes of lower back pain treatments can vary from person to person‚ so it is generally advisable to get

EXPERIMENT 3: INTRODUCTION TO TITRATION – DETERMINATION OF THE MOLARITY AND CONCENTRATION OF SULPHURIC ACID BY TITRATION WITH A STANDARD SOLUTION OF SODIUM HYDROXIDE INTRODUCTION Reaction of acid and base is one of the most common reaction in chemistry. This reaction is also widely known as neutralization. In this experiment‚ we used titration technique which involves accurately measuring the volume of a solution required to react with another reagent. An indicator must be used to determine the

Elvin Banuelos Back to Representation Robert Zemeckis’s Back to the future takes place during the 1950’s‚ a time when capitalism was on the rise in America. It serves a greater purpose than showing what it’s like for Marty Mcfly to travel back in time‚ but rather real events which had occurred prior to the 1950’s‚ including the beginning of the Cold war versus the Soviet Union. The movie serves as a good representation on how this country has changed its way of thinking from the 50’s until the

John Collier BACK FOR CHRISTMAS Interpretation The story “Back for Christmas” was written by a highly skilled modern English writer John Collier (3 May 1901 – 6 April 1980). His stories may be broadly classified as fantasies‚ but are really sui generis. They feature an acerbic wit and are usually ironic or dark in tone. His distinction is a grotesque with a twist in the end. This author can stands a picture vivid before the eyes of the reader. The title of the story under analysis is short but
