Potassium dichromate (K2Cr2O7) is a basic salt.
Potassium bromate is a basic salt.

3KBrO3 + AlPO4 ------> K3PO4 + Al(BrO3)3
No, bromate is not a metal, but is an ion
Yes, it is
Potassium hydroxide is the most common. J Ayres
potassium bromate
Potassium bromate, KBrO3 is the salt of a strong base and a semi weak acid. So the salt will be alkaline (pH >7) upon dissolution.
Dissolve 128 mg of potassium bromate in 100 ml of deionised water

Sodium bromate was ingested by hair dressers in Japan in a suicide attempt. One of the things that this caused was kidney failure. Excesses of potassium, sodium and bromate ions are all passed via the kidney. Bromate is an oxidizer, and will reduce fairly easily to bromide ion oxidizing whatever it can with pH changes. Excess potassium (whether or not with the bromate anion) is an issue for people with kidney problems. Potassium bromate is sometimes mixed in flour when bread is made. It looks like flour. Baking converts most of the bromate to bromide. If the mixing is not thorough, potassium bromide / bromate can be ingested in large quantities. So it is a "leading contributor" only because it has a known use in the human food chain.
Flour often contains potassium bromate which is added to help it rise better in recipes.
Potassium bromate
Potassium bromate is added to enhance the rising characteristics of the dough. It is an oxygen source. What has not been harvested for its oxygen content by yeast, breaks down to potassium bromide upon (fully) baking the dough into bread. Most countries have banned its use, starting in the 1990's, because some organisms develop cancer when they consume potassium bromate. Its use here has largely been replaced with ascorbic acid (and other selections). Potassium bromate is also used to "modify" barley malt used in brewing. Sodium bromate is used in permanent wave solution.
