Bilgi kutusu kaynakları

Potasyum hidroksit ya da potasyum hidrat bir kimyasal bileşik. Akkor derecede uçucu olan, 360 °C'de eriyen, suda ısı açığa çıkararak çözünen, beyaz renkte katı bir maddedir. Alkalik bir baz olan potasyum hidroksidin geniş bir kullanım alanı vardır. Endüstride arap sabunu üretiminde, pillerde elektrolit olarak ve gübre yapımında kullanılır.

Potasyum hidroksit tarımda asidik toprakların pH derecesini dengelemek alkalik yapmak amacıyla sıkça kullanılır. Ayrıca tarım ilaçlarının yapımında da kullanılır. Bunun yanında tıpta, endüstriyel kimyada da kullanılır.

Potasyum hidroksit endüstriyel kimyada geniş kullanım alanlarına sahiptir. Geri dönüşümlü kâğıtların yapımında, sıvı sabun yapımında ve birçok temizlik ürününün üretiminde potasyum hidroksitten yararlanılır.

Ayrıca veteriner hekimliğinde bazı hayvan ilaçlarının yapımında kullanılmaktadır. Potasyum hidroksit CO2 tutucudur, bu yüzden bileşikten bitkisel deneylerde yararlanılmaktadır.
