A student plans to titrate 25.00ml of a 0.134M HNO3 solution with a 0.179M NaOH solution. Calculate the volume of NaOH(in ml) that will be needed to reach the equivalence point and anticipated pH.
25.0ml of a 4.21M HCL solution at 25.2C and 50.0ml of a 2.2M NaOH solution at 25.2C are reacted together to give a temperature of 44.1C.
