Ku saabsan Kalkaaliyahan
The pH scale measures how acidic or basic a solution is, defined as the negative base-10 logarithm of the hydrogen-ion concentration: pH = −log₁₀[H⁺], where [H⁺] is in moles per litre. Because it is logarithmic, each whole pH unit is a tenfold change in acidity — a pH 4 solution has ten times the [H⁺] of pH 5 and a hundred times that of pH 6. The scale runs from strongly acidic near 0, through neutral at 7, to strongly basic near 14. This calculator converts a concentration to pH, a pH back to concentration, or starts from pOH.
As a worked example, pure water has [H⁺] = 1 × 10⁻⁷ mol/L, so pH = −log₁₀(10⁻⁷) = 7, which is neutral. A solution with [H⁺] = 10⁻³ mol/L has pH 3 and is acidic; one with pH 11 is strongly basic. The tool also returns pOH and the hydroxide concentration [OH⁻], using the water relationship pH + pOH = 14 at 25 °C — so pH 3 implies pOH 11 and [OH⁻] = 10⁻¹¹ mol/L — and labels the result acidic, neutral or basic.
pH governs a huge range of everyday and industrial processes: the safety of drinking water and swimming pools, soil conditions for gardening, food preservation and brewing, the action of enzymes in the body (blood is tightly held near pH 7.4), and countless chemistry and biology experiments. Note that the 14-point span and the pH + pOH = 14 rule are specific to 25 °C; at other temperatures the neutral point and the sum shift slightly because water’s self-ionisation changes.
Su'aalaha badanaa la isweydiiyo
Waa maxay pH-ka?
pH waa logarithm-ka aasaaska-10 ee logarithm-ka hydrogen-ion, pH = -log₁₀[H⁺]. Ku-dhaca 1 × 10⁻⁷ mol / L wuxuu siiyaa pH-ka midab-la'aanta ah ee 7.
Sidee pH iyo pOH la xiriira?
Marka 25 °C, pH + pOH = 14. Sidaa darteed xalka pH 3 wuxuu leeyahay pOH 11, iyo isku darka hydroxide waa [OH⁻] = 10⁻¹¹ mol / L.
Maxaa micnaheedu yahay pH-ka?
Ka hooseeya 7 waa acidic, si toos ah 7 waa midab la'aan, iyo kor 7 waa aasaasiga ah (alkaline). Miisaanka caadi ahaan socda 0-14, in kastoo acids aad u xoog badan ama daboolka ka mid ah waxay ku dhici kartaa si yar ka baxsan.
Maxaa pH logarithmic ah?
Hydrogen-ion concentrations ku faafay amarro badan oo weyn, sidaas darteed log scale siinaya tirada maamuli kara. Unit kasta oo ah isbedelka toban jeer: pH 4 waa toban jeer acidic ka badan pH 5 iyo boqol jeer ka badan pH 6.
Sideen u heli karaa [H⁺] ka pH qiimaha?
Invert definition: [H⁺] = 10^(−pH). pH of 3 siiyaa [H⁺] = 10⁻³ = 0.001 mol/L. Dooro "oo ka mid ah qiimaha pH" qaabka iyo xisaabinta ku soo laabtay tirada aad u.
Ma pH-ku wuu isbedelaa marka heerkulku kordho?
Haa. Dhinaca midabka 7 iyo pH + pOH = 14 xeerka haysta 25 ° C; heerkulka sare ee biyaha ionizes in ka badan, sidaas daraaddeed pH midabka hoos u dhac 7 iyo tirada hoos u dhac yar.
