where "K a" is the equilibrium constant for the ionization of the acid. Example: What is the pK a of acetic acid, if K a for acetic acid is 1.78 x 10-5? pK a = - log (1.78 x 10-5) = - ( - 4.75) = 4.75 Top. Calculating K a from the pK a. The K a for an acid is calculated from the pK a by performing the reverse of the mathematical operation used

For example, sulfuric acid (H 2 SO 4) has two ionizable protons (H +) which can participate in the neutralization of a base such as sodium hydroxide (NaOH) H 2 SO 4 (aq) + 2 NaOH → 2 Na + (aq) + 2 H 2 O + SO 4 2+ (aq) If a sulfuric acid solution is 1 M, then it is 2 N expressed as normality.

Example: The K a for acetic acid is 1.7 x 10-5. What is the value of K b for the acetate ion? (1.7 x 10-5)(K b) = 1 x 10-14 K b = 5.9 x 10-10. Example: The K b for aniline is 3.8 x 10-10. What is the value of K a for the anilonium ion? (K a)(3.8 x 10-10) = 1 x 10-14 K a = 2.6 x 10-5…

Sulfuric acid - Wikipedia

Sulfuric acid or sulphuric acid, also known as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula H2SO4. It is a colorless, odorless and viscous liquid that is miscible with water. Pure sulfuric acid does not exist naturally on Earth due to its strong affinity to water vapor; for this reason, it is hygroscopic and readily absorbs water vapor from the air. Concentrated sulfuric acid …

Despite this fact, many industries prefer using carbon steel due to its low cost. Figure 1 shows

Corrosion tables — Materials Technology

The corrosion data in this section is mainly based on the results of general corrosion laboratory tests, which are not strictly comparable with actual service conditions.The corrosion tables provide an initial guide to the selection of materials and are intended to facilitate understanding of the different types of corrosion damage that can arise due to poor material selection.

The pH Scale - GitHub Pages

pH is a logarithmic scale. A solution that has a pH of 1.0 has 10 times the [H +] as a solution with a pH of 2.0, which in turn has 10 times the [H +] as a solution with a pH of 3.0 and so forth.. Using the definition of pH, it is also possible to calculate [H +] (and [OH −]) from pH and vice versa.The general formula for determining [H +] from pH is as follows:

Percent composition in chemistry typically refers to the percent each element is of the compound''s total mass.. The basic equation = mass of element / mass of compound X 100%. For instance, if you had a 80.0 g sample of a compound that was 20.0 g element X and 60.0 g element y then the percent composition of each element would be:
