... acids ionize in water to form H+ ions more precisely, the H from the acid molecule is donated to a water molecule to form hydronium ion, H3O+. A proton (H+) cannot exist on its own in water! bases dissociate in water to form OH ions bases, such as NH3, that do not contain OH ions, produce OH by p ...

Writing Linear Equations in Slope-Intercept Form
... Note to the Teacher The slope-intercept form is a special case of the point-slope form. The given point of the line (x0, y0) lies on the y-axis, so x0 0. This means that the equation is of the form y y0 mx, or y mx y0. The equation is therefore given explicitly when both the y-intercept an ...
