writing equation

Postby Sarah Blake-2I » Wed Dec 04, 2019 2:22 am

Could someone walk me through how to write out an equation to find out if the solution is acidic or basic? For instance KF in water. How would you write the chemical equation for this and how do you know if it will produce hydronium or hydroxide?

Group 1 elements do not affect the pH, so we can leave out potassium in the equation.

F- + H20 ------> HF + OH-

Since F-, gained a proton, KF would be considered basic. The reason this cannot form a hydronium ion is because KF has no hydrogen to donate to water.
