Hydronium ion, H3O+, is what gives a low pH to an aqueous solution. Hydronium ion is made when an acid donates a hydrogen ion to a water molecule.    Hydroxide ion, OH- â¦ , gives a higher pH to an aqueous solution. Hydroxide ions are found in bases; a base donates hydroxide ions to water.   Combining H3O+ + OH-makes 2 H2O.he hydronium ion is a polyatomic ion that forms when an acid releases a proton (H+) to a water molecule.
For the most part, the media seems to grasp the key features of electric-car maker Tesla Motors' (NASDAQ:TSLA) new Model X -- at least all features except for one critical element: price. Most media outlets are still asserting the Model X will start at $132,000. But this figure is off by quite a bit.

It might be slightly higher, but... I can't imagine that it will be... It's probably going to be a slightly higher starting price because the Model X will only be offered as all-wheel drive. It will be dual motor, all-wheel drive. The stuff about the Model X starts at about the 24:00 mark. Yes, I know it was recorded with a potato.
