To determine the oxidation number of an atom(s) in a molecule or an ion, start with the known oxidation numbers and the rules summarized below: Keep in mind that the summary is zero for neutral molecules and is equal to … Read more
To determine if CH3Cl is polar or nonpolar, we need to first determine its geometry. This presumes knowing the rules for drawing a correct Lewis structure and you can find more details about Lewis structures here. CH3Cl has 4 + 3 … Read more
To determine if SO2 (sulfur dioxide) is polar or nonpolar, we need to first determine its geometry. This presumes knowing the rules for drawing a correct Lewis structure and you can find more details about Lewis structures here. Sulfur is … Read more
First, we need to draw the Lewis structure of CH3+. In short, these are the steps you need to follow for drawing a Lewis structure: 1. Write the correct skeletal structure for the molecule. * Hydrogen atoms are always … Read more
First, we need to draw the Lewis structure of IF5. In short, these are the steps you need to follow for drawing a Lewis structure: 1. Write the correct skeletal structure for the molecule. * Hydrogen atoms are always … Read more
First, we need to draw the Lewis structure of C2H4. In short, these are the steps you need to follow for drawing a Lewis structure: 1. Write the correct skeletal structure for the molecule. * Hydrogen atoms are always … Read more
First, we need to draw the Lewis structure of H2O. In short, these are the steps you need to follow for drawing a Lewis structure: 1. Write the correct skeletal structure for the molecule. * Hydrogen atoms are always … Read more
In the previous few posts, we have been discussing acid-base titrations involving pH calculations and analyzing the titrations curves. A typical acid-base titration curve can be obtained, for example, based on the reaction of HCl and NaOH: Check … Read more
In the previous post, we discussed the titration of a weak acid, CH3CO2H with a strong base, NaOH. The main difference compared to the strong acid-base titrations was that the conjugate base of the weak acid, forming during the reaction … Read more
In the previous post, we discussed the titration of 25.0 mL of 0.100 M strong acid HCl with 0.100 M NaOH. Today, we will focus on the titration of a weak acid with strong bases, so we can still use … Read more
