WitrynaB Because each formula unit of NaOH produces one Na + ion and one OH − ion, the concentration of each ion is the same as the concentration of NaOH: [Na +] = 0.21 M and [OH −] = 0.21 M. A The formula (CH 3) 2 CHOH represents 2-propanol (isopropyl alcohol) and contains the –OH group, so it is an alcohol. Witryna7 kwi 2024 · sodium hydroxide (NaOH), also called caustic soda or lye, a corrosive white crystalline solid that contains the Na + cation and the OH − anion. It readily … WitrynaCalculate the amount of sodium hydroxide, NaOH, in 25.0 cm3 of solution of concentration 0.1 mol/dm3. Converting the volume from cm3 to dm3, 25.0 cm3 = 25.0 ÷ 1000 = 0.025 dm3.
