Ph of kbr
WebJan 31, 2024 · pH is a measure of acidity or alkalinity that indicates the a mount of hydrogen ions present in a solution or substance. The pH is defined as the negative base 10 logarithm of the activity of hydrogen ions, that is, the concentration of hydrogen ions or H₃O⁺: pH= - log [H⁺]= - log [H₃O⁺] Definition of pOH WebFeb 10, 2024 · pH = 14 +log(0.05) = 12.7 −−− − The answer is rounded to one decimal place because you have one significant figure for the concentrations of the two solutions. Finally, to find the mass of aqueous potassium bromide produced by the reaction, use the compound's molar mass 0.025moles KBr ⋅ 119.002 g 1mole KBr = 3 g −−
