Potassium chlorate is the inorganic compound with the molecular formula KClO 3. In its pure form, it is a white solid. In its pure form, it is a white solid. After sodium chlorate , it is the second most common chlorate in industrial use.
For that reason, it has been largely replaced by the potassium perchlorate mixtures. Chlorate mixes are still used when cost is the overriding concern because potassium chlorate is less expensive than perchlorate. The simplest is a two-component chlorate mix, although this is rarely used. KClO 3 + 2Al → Al 2 O 3 + KCl
Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. [7]
Potassium perchlorate – common, relatively stable. Almost non-hygroscopic. Low solubility in water. Produces high temperature flame and smoke of potassium chloride. Safer replacement of potassium chlorate. Impact-sensitive with phosphorus,
As an oxidizer, potassium perchlorate can be used safely in the presence of sulfur, whereas potassium chlorate cannot. The greater reactivity of chlorate is typical – perchlorates are kinetically poorer oxidants. Chlorate produces chloric acid (HClO 3), which is highly unstable and can lead to premature ignition of the composition.
Three employees at a Maryland Cracker Barrel have reportedly been dismissed after staff refused to seat a group of students with special needs on Dec. 3.
In the early morning hours of Dec. 26, 1996, Patsy Ramsey called 911 to report her 6-year-old daughter JonBenét missing, and found a rambling ransom note left inside their Boulder, Colorado, home.
They contain the (ClO 3 −) anion. The stock naming convention distinguishes four chlorates, based on the oxidation state of the chlorine within the oxyanion. The stock and common names are: Chlorate(I) = Hypochlorite; Chlorate(III) = Chlorite; Chlorate(V) = Chlorate; Chlorate(VII) = Perchlorate
