CSEC Chemistry Paper 2 Acids, Bases & Salts-Salts Preparation (Are we there yet?) Picking up from if the salt we are making is not an anhydrous chloride (a binary dry salt), then the next question to ask is,?Is the salt a soluble salt?? We are going the opposite of the order in which solubility was […]

CSEC Chemistry (May 13, 2020) Acids, Bases & Salts: The Missing Piece- Concentration vs Strength If you really have been seriously reviewing this topic, even if you are looking at it for the first time, you would have come upon the term, “strong” and “weak” acids and alkalis. As a child, when tasked with making […]

CSEC Chemistry Paper 2 (May 12, 2020) Daily Revision is again from Acids, Bases & Salts (ABS)-The Basics of Bases Having looked at acids, it is natural/automatic that we put “2” and “2” together to figure out bases. The two terms, acids and bases, go together like biceps and triceps, from Biology and debit and […]

CSEC Chemistry Paper 2 (May 11, 2020) Daily Revision is again from Acids, Bases & Salts (ABS) The word acid comes from Latin acidus which means sour tasting. This isn’t necessarily the best way to start a definition or do an intro to a Chemistry term since we MUST NEVER TASTE ANYTHING IN THE LAB […]

Chemistry Revision 1

CSEC Chemistry Paper 2 (May 10, 2020) Daily revision is from Acids, Bases & Salts. Acid anhydride literally means acid “without hydrogen” or what we would call a “dry acid” since the hydrogen is coming fro the water. (See below) (Prefix ‘an” means without and “hydride” from word which means hydrogen. The formal definition is […]
