Question

Write, Balance and Label the type of reaction:
Potassium Hydroxide plus phosphoric acid yields potassium phosphate and water

Help me understand this?

Answer 1

neutralisation.

Answer 2

KOH + H3PO4 -> H2O + K3PO4

Answer 3

there are several method used to balnce equations would you like a more general one?
What grade are you in?Have you done any method in class?

Answer 5

10th grade. The tip our teacher gave us was to leave Hydrogens and Oxygens last. I'm just struggling at this point with the Balancing.

Answer 6

To balance look at everything but the hydroxide and hydrogen atoms

KOH + H3PO4 -> H2O + K3PO4
Left side has 1K and right side has 3K
PO4 is 1 to 1

so balance potassium first, now count the amount of hydrogen and oxygen atoms on both sides

3KOH + H3PO4 -> H2O + K3PO4
Left side
3 oxygen, 3 hydrogen, 3hydrogen = 3 oxygen + 6 hydrogen = 3 water molecules

Right side
2hydrogen + 1oxygen = 1 water molecule

so we need to increase the amount of molecules of water on the right side to by 3

so we have

3KOH + H3PO4 -> 3H2O + K3PO4

Answer 7

okay..balancing at you level is a hit and trial game.....but here are some general pointers.
1)first try to balance out all the unique/non basic element in this case Potassium and Phosphorus.
2)balance out the remaining elements in order of complexity ...i.e.complexity is the number of compounds an element is a part of in the reaction
3)very high complexity elements will generally be O,H,C,etc balance these out last!.Remember that you can add co2 or h2o to balance these elements out.

Answer 8

note that later on you'll learn of concept like oxidation,reduction etc which will make your life a whole lot easier.
