WebThat is the hydrohelium (1+) cation, \(\ce{HeH^{+}}\), which is a positively charged ion formed by the reaction of a proton with a helium atom in the gas phase. It was first produced in the laboratory in 1925 and is isoelectronic with molecular hydrogen (\ce{H2}}). It is the strongest known acid, with a proton affinity of 177.8 kJ/mol.

WebAn amphiprotic molecule (or ion) can either donate or accept a proton, thus acting either as an acid or a base. Water, amino acids, hydrogencarbonate ion (or bicarbonate ion) HCO− 3, dihydrogen phosphate ion H2PO− 4, and hydrogensulfate ion (or bisulfate ion) HSO− 4 are common examples of amphiprotic species. WebNov 4, 2024 · The use of conjugate acid-base pairs allows us to make a very simple statement about relative strengths of acids and bases. The stronger an acid, the weaker its conjugate base, and, conversely, the stronger a base, the weaker its conjugate acid. TABLE 11.13. 1: Important Conjugate Acid-Base Pairs. Table 11.13. 1 gives a list of some of …
