Apa formula pH?
pH nyaéta logaritma basis-10 negatif tina konsentrasi ion hidrogen, pH = −log₁₀[H⁺]. konsentrasi 1×10⁻⁷ mol/L méré pH netral 7.
Apa hubungane pH lan pOH?
Ing 25 °C, pH + pOH = 14. Satemah larutan pH 3 duwé pOH 11, lan konsentrasi hidroksidané ya iku [OH⁻] = 10⁻¹¹ mol/L.
Apa tegese skala pH?
Di handapeun 7 nyaéta asam, tepatna 7 nyaéta netral, sarta di luhur 7 nyaéta basa (alkali). Skala biasana dijalankeun 0-14, sanajan asam atawa basa anu kuat bisa kaleungitan saeutik di luar éta. Kalkulator ngaklasifikasikeun nilai anjeun salaku asam, netral atawa basa.
Apa tegese pH?
Hidrogén-ion konsentrasi span loba urutan tina magnitude, jadi skala log tetep angka manageable. Satiap unit nyaeta hiji pamutahiran puluh kali: pH 4 is ten times more acidic than pH 5 and a hundred times more than pH 6.
Carane aku nemokake [H⁺] saka nilai pH?
Ngabalikkeun pangaweruh: [H⁺] = 10^(−pH). pH 3 mawa [H⁺] = 10⁻³ = 0.001 mol/L. Pilih mode "ti nilai pH" sarta kalkulator bakal balikkeun konsentrasi pikeun anjeun.
pH bisa diukur kanthi suhu.
Ya. Poin netral 7 sarta aturan pH + pOH = 14 tetep dina 25 °C; dina suhu luhur cai leuwih ionisasi, jadi pH netral turun ka handap 7 sarta jumlahna turun saeutik. Alat ieu ngagunakeun nilai standar 25 °C.
