Abstract

Penelitian ini menggunakan metode eksperimen. Objek penelitian menggunakan plat baja karbon rendah st 37 dengan ukuran spesimen 50 mm x 40 mm x 3 mm. Menggunakan metode perendaman spesimen dalam wadah uji dengan volume 250 ml dari setiap wadah uji. Untuk perendaman dalam larutan asam klorida, sulfat, asetat, larutan garam. laju korosi terbesar adalah terjadi pada asam klorida dengan kehilangan berat sebesar 35,91 gram dengan konsentrasi 35%. dan laju korosi terkecil terjadi pada garam, untuk perendaman dalam larutan garam kehilangan beratnya adalah 0,20 gram dengan konsentrasi 20%. Penelitian ini dilakukan selama 14 hari perendaman. Berdasarkan hasil perhitungan dari data dengan metode weight loss diproleh, dapat di analisa bahwa larutan yang paling cepat terjadi laju korosi adalah asam. Klorida konsentrasi 35% dari reaksi diatas dapat dijelaskan bahwa semakin besar konsentrasi asam klorida maka semakin banyak atom atom yang terlepas dari besi sehingga kecepatan korosi semakin besar.
