Density of Sulfuric Acid

In Germany and France the Baumii scale is calculated using 144.3 as the constant. The Baumii scale only includes the sulfuric acid concentration range of 0—93.19% H2SO. Higher concentrations are not included in the Baumh scale because density is not a unique function of concentration between 93% and 100% acid. The density of sulfuric acid versus temperature and concentration is shown in Figure 4 (50).

When the battery is discharging, metallic lead oxidizes into lead sulfate and lead oxide is reduced to lead sulfate. Therefore, lead sulfate forms at both electrodes. At the same time, sulfuric acid is consumed and water is produced so that the density of sulfuric acid falls as discharging progresses. The state of the battery s charge can then be determined by this change of density.

The mass of per unit volume of a substance is called the density of the substance. Its symbol is p, and the unit is kg/m or g/cm. When talking about daisity, temperature must be specified because the volume of the substance is changed with changing temperature due to thermal expansion and contraction. For example, the density of sulfuric acid is quite different at different temperatures. The densities of 38% sulfuric acid are 1.293,1.286, and 1.278 when the tanperatures are 10°C, 20°C, and 30°C, respectively. In this sense, when we prepare a sulfuric acid solution with a desired density, temperature should be controlled carefully. With respect to this. Table 5.2 should be very useful. 

In a lead-acid battery, when the charge is completed, the density of sulfuric acid electrolyte solution is between 1.2800 and 1.2900 g/cm. However, when the...

An Ostwald viscometCT consists of a capiltary tube through which a fixed volume of a liquid is allowed to flow under hydrostatic pressure. If in a cafain viscometCT the fixed volume of watCT requires 215.3 s to flow at 20°C, calculate the time required for this volume of sulfuric acid to flow at 20°C. Use the fact that the hydrostatic force in a given viscometer is proportional to the density of the liquid. The density of sulfuric acid is...
