H B H H A H H What do we call the bonds labelled A and B? Covalent bond, hydrogen bond Hydrogen bond, ionic bond lonic bond, covalent bond Hydrogen bond, covalent bond H

Draw a diagram of a water molecule. Show all valence electrons, lone pairs, molecular geometry, and partial charges.

Pure water has a pH of 7, the point at which the concentrations of hydrogen ions and hydroxide ions are equal and water is considered to have neutral pH. If an acid is added to water, the pH value because the acid releases goes up above 7 ; hydrogen ions goes down below 7; hydrogen ions goes up above 7; hydroxide ions goes down below 7 ; hydroxide ions
