k) pH: 6.0 This hazardous product is a weak acid since its pH is 6.0. This means that
the hazardous product is not likely to be highly corrosive (not likely to
degrade/eat away at living tissues, metals and other materials).
l) Kinematic Viscosity: Data not available.
m) Solubility: Soluble in Water at 25 °C (77 °F) This hazardous product can dissolve in water more readily. This information
can be used for spill response and fire fighting procedures.
n) Partition Coefficient, n-Octanol/Water (Log Kow): -0.85 Since the Partition Coefficient (Log Kow = -0.85) is less than 1, this
indicates that this product dissolves more easily in water. It also means that
this product is not easily absorbed or stored in fatty tissues of the body.
o) Vapor Pressure: 129 mm Hg at 25 °C (77 °F) This hazardous product has a high Vapor Pressure (as a point of reference,
water has a low vapor pressure with 23.8 mmHg at 25 °C). The higher
the vapor pressure, the higher the potential for the hazardous product
to become a vapor or gas. Products with high vapor pressures are more
dangerous as they can become airborne (inhaled and catch fire) more easily.
p) Density and Relative Density
– 0.782-0.790 g/mL at 25 °C (77 °F)
This hazardous product is less dense than water (as a point of reference,
the density of water is 0.9970 g/mL at 25 °C). This indicates the following:
– Floats on water.
– Can catch fire and spread flames more easily.
– May spread through the air and water more easily.
q) Relative Vapor Density: 1.11 This hazardous product's Vapor Density is heavier than air (1.11 > 1.0) and
will sink. This indicates the following:
– Vapors can flow along the ground and collect in low-lying areas or
depressions.
– Vapors can sink until it is at a concentration sufficent for ignition.
– Vapors can collect to cause the displacement of air, presenting a risk of
suffocation (especially in confined spaces).
r) Particle Characteristics: No data available relating to
particle size and distribution.
9.2 Other Information
Vapors may form explosive mixtures with air.
