Adjusting pH in Water
Pure or distilled water has a pH level of 7, which means it is neutral. If you want to increase the pH of water, you must add an alkaline substance, such as baking powder, to it. If you want to decrease the pH of water, you add an acidic substance, such as lemon juice, to it
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Mol h2so4=0,6x3=1,8mol
MolOH-=Mol H+=2molh2so4=1,8x2=3,6mol
=> Mol NaOH=3,6mol=>V naoh= 3,6:4=0,9liters.
So, A is the correct answer
