Question about acetate buffer

This is the long and computational answer to Debra's question about what happens when 100 mmol of HCl ispoured into an 100 ml acetate buffer (0.2 M)


Ions and compounds Atoms are made up of neutrons that are neutral and have no charge, protons with a positive charge andelectrons with a negative charge.An ion is an entity or a group of atoms with a positive or negative charge such as the positively charged hydrogen ion H+ and thenegatively charged nitrate ion NO3-. Negatively charged ions are also...

Questions & Answers Question about acetate buffer and what happens when HCl is added to such a solutionDebra ask:How do I attack this problem?I want to compare the effect of adding 1mmol of HCL to 100 ml of 0.2M acetate buffer at two different starting pH's. (pKa of acetate buffer =4.7Initial pH = 4.7Initial pH = 5.7Thank youHi Debra,There is bo...

An introduction to Ionic Strength BackgroundTo quantify the effect of inter-ionic interactions, such as molecular attraction and repelling, one has to have a `parameter` describing themagnitude of these forces and how they alter the way certain calculation are done.Topic: Equilibriums The pH s...

NaHCO3 dissolved in water - how is pH calculated? Background about buffersA buffer is a solution that has the ability to keep pH within a certain and narrow range: even if an excessof hydrogen ions (H+) is applied to the solution. In other words:buffers resist changes in pH whenreasonable amount of either H+ or OH- is added to the buffer solution.Th...
