Problem- How many moles of H+ or OH- ions are there in 3 moles of H2SO4? In 0.2 mole of NaOH? In 1 mole of H3PO4 assume H3PO4 has 3 H+ ions per molecule?
Explain the each and every step in detail for help
The rate constant at 25oC is 3.7×10^9 mol^-1 L s^-1. In an experiment, 0.500 L of 0.020 mol L ^-1 NaOH(aq) is rapidly mixed with an equal volume of 0.020 mol L^-1 HCN(aq). Calculate the time, in seconds, required for this [OH] to decrease to 1.0×1..
