  • Online Middle School Chemistry Resource

    Updated: 2012-03-31 22:28:52
    The ACS Education Division has developed a new middle school chemistry resource, "Middle School Chemistry: Big Ideas about the Very Small." This free, six-chapter resource can serve as either a stand-alone chemistry unit or as a supplement to any middle school science curriculum. "Middle School Chemistry" uses a hands-on inquiry approach along with specially designed molecular model animations, to take students from concrete experiences to an understanding of the world of atoms and molecules. Share this free resource with middle school teachers you know.

    Are you familiar with the "I.C.E. method" and do you know how to write an equilibrium expression for a weak acid? 

  • calculationg actual concentration given pH and total concentration

    Updated: 2012-03-31 20:47:38
    Im not sure on how to approach the problem. Assuing the reaction isHC3H3O2  H+ + C2H3O2-used the measured pH (2.42) and the total concentration (.1M) to calculate the actual concentration of each species. Im not really sure where to start on this problem. please give me a push. i dont want the answer. just a hint on where to start. thankyou for helping.

    originally you said that "For 2 moles of water, 2 electrons are spent" and that you "got two times more moles than I should, to get the right answer"now we figured out that for 2 moles of water, 4 electrons are spent and you still get the wrong answer. this seems suspect.

    Skepticism plays a central role in any kind of scientific research. To paraphrase Feynman, you should try never to fool yourself - and you are the easiest person to fool! We chemists all want to believe in the high yield, or the perfect recrystallization that causes us to turn cartwheels…until we realize that we can’t repeat [...]

    Updated: 2012-03-25 00:56:58
    As many of you may have noticed the posting traffic on chemistry-blog.com has slowed as of late. One of the risks associated with any blog is the correlation between the number of posts and visitors: as the number of post goes down, so does the traffic. Allowing this downward spiral to continue can ultimately result [...]

    I forget that ChemFeeds allows me a very unique window into the popularity of various chemistry articles across chemistry publishers (e.g., ACS, RSC, Nature). For February, the most popular article was an editorial penned by Roald Hoffmann critiquing the chemistry community's response to the 2011 chemistry Nobel prize. What, Another Nobel Prize in Chemistry to [...]

  • O-Level Chemistry: Redox Reactions (Reduction & Oxidation) – Hydrogen Atoms

    Updated: 2012-02-29 22:51:14
    In the previous post, you have learnt that OXIDATION is the gain of  oxygen atoms and REDUCTION is the loss of oxygen atoms. Today, we shall discuss them based on the gain or loss of hydrogen atoms. OXIDATION is also the loss of hydrogen atoms and REDUCTION is also the gain of hydrogen atoms. E.g....

  • O-Level Chemistry: Redox Reactions (Reduction & Oxidation) – Oxygen Atoms

    Updated: 2012-02-27 15:35:49
    REDOX reactions are reactions that involves both Reduction & Oxidation simultaneously. There are 4 ways to look at whether a substance has been oxidised or reduced, and they are: 1. Gain/Loss of Oxygen atoms 2. Gain/ Loss of Hydrogen atoms 3. Gain/Loss of Electrons 4. Increase/Decrease in Oxidation States/Numbers Today we will discuss Oxidation /...
