<p><b>Halaman baru</b></p><div>'''Asam perteknetat''' (HTcO<sub>4</sub>) adalah sebuah [[senyawa kimia|senyawa]] [[teknesium]] yang dihasilkan dengan mereaksikan [[teknesium(VII) oksida]] (Tc<sub>2</sub>O<sub>7</sub>) dengan air atau [[asam oksidator]] kuat, seperti [[asam nitrat]], [[asam sulfat]] pekat, atau [[air raja]]. Substansi [[Higroskopi|higroskopis]] berwarna merah tua adalah asam kuat, dengan [[Konstanta disosiasi asam|p''K''<sub>a</sub>]] sebesar 0,32, karena hampir seluruhnya eksis sebagai ion [[perteknetat]] dalam larutan berair. Warna merah pada larutan diduga karena terbentuknya [[polioksometalat]] .<br />
<br />
Penggunaan larutan asam yang cukup kuat, misalnya asam sulfat pekat, dapat menghasilkan bentuk terprotonasi, yang kemudian menjadi kompleks oktahedron TcO<sub>3</sub>(OH)(H<sub>2</sub>O)<sub>2</sub> di[[hidrat]].<br />
