A fire truck attaches two fire hoses to a hydrant to fight a fire. Each hose has a diameter of 20 cm. The underground water pipe going to the hydrant has a diameter of 100 cm. In the underground pipe, the water has a speed of 2.0 m/s.
Does the [H+]=[OH-] at the midpoint or the equivalence point?
What does it mean for something do to be neutralized? Is that when the [H+]=[OH-]? or is that totally wrong?
