In a solution of 0.015 mol L HBr(aq) at 25 °C (a) What are the concentrations of the hydronium, H,O', and hydroxide, OH, lons? [H,O']= Number mol L [OH] = Number mol L1 *Recall that HBr is a strong acid which means it completely lonizes in water * Syntax for scientific notation is 1.23 x 10 is 1.23E4 and 1.23 x 10 is 1.23E-4 (b) What is the pH of the solution? Number *Note that all iogarithms have two parts. The decimal part is called the mantissa. The digits in the mantissa are the only significan figures in a logarithm. The integer, or characteristic, is the power to which the base is raised when writing the number in scientific notation. It is an exponent and therefore not a significant figure.
