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.
According to a company statement, Model S buyers who use a referral link from a current Tesla owner will receive a discount of $1,000 off the purchase price of the car.udging by the feedback from its owners, Tesla brand advocates abound. While $1,000 does not seem like a difference-maker for this class of car enthusiasts, a trip to the Gigafactory launch and a shot at a special-edition Model X seem like they would be right up the alley of Teslaâs biggest fans.
