a what is any substance that can accept a hydrogen ion
confidence votes 119 bases are hydrogen proton acceptors and acids are hydrogen proton donators bases are hydrogen proton acceptors and acids are hydrogen proton donators exists and is an alternate of bases are hydrogen proton acceptors and acids are hydrogen proton donators bases are hydrogen proton acceptors and acids are hydrogen proton donators minor edit when this happens the covalent bond is broken and a hydrogen ion positive charge because it lost its electron to oxygen shorthand h+ is released the remaining part of the original water molecule is called a hydroxide ion negative charge because it kept an extra electron shorthand oh although present at very low levels in solution h+ and oh ions can have enormous effects on the properties of a solution especially when they are not in balance in pure water every hydroxide ion that forms creates a hydrogen ion so there are equal numbers of anions and cations if a solute is added to water however this balance can change hydrochloric acid hcl is a molecular compound that dissociates separates easily because chlorine is so strongly electronegative a brønsted lowry base is one that accepts a proton which becomes part of the molecule once a proton is accepted the particle is then capable of donating that proton to something else donating a proton is an act of a brønsted lowry acid on the other hand an arrhenius acid tends to donate hydrogen ions or accept hydroxide ions recall that ph is a measure of the reciprocal note the negative sign and the logarithm of the hydrogen ion concentration in solution defined by the following equation ph log h+ the arrhenius definition of a base is a species that tends to donate hydroxide ions or accept hydrogen ions in solution on the other hand an arrhenius acid tends to donate hydrogen ions or accept hydroxide ions therefore as you guessed when hydrogen ion concentration decreases ph increases the h3o ion is called a hydronium ion and this alternate definition of ph is equivalent to the first to see why consider what actually happens when an arrhenius acid dissociates in an aqueous water containing solution ha h2o a h3o in this reaction ha is the acid and a is its conjugate base the ph of pure water is 7 which represents 1 x 10 7 hydrogen ions for every one intact water molecule this is only one h+ ion for every 10 million h2o molecules in the ph scale as h+ ion concentration increases ph values decrease a buffer is any substance that minimizes change in the ph of a solution most buffers consist of a combination of a weak acid and the weak base where the base is the anion remaining after the weak acid dissociates separates to release h+ ions what is produced when an acid reacts with a base points 3 acid base salt and water gas 4 which of the following is arrhenius s definition of an acid points 3 a substance that dissociates in water to produce hydroxide ions oh a substance
The Arrhenius
