Calculate pH of HCl using pH equation Because HCl is a strong acid, it dissociates completely to H + and Cl - ions in the water. HCl → H + + Cl - According to the stoichiometric ratios, H + concentration equals to the HCl concentration. Therefore, we can directly substitute HCl concentration to pH equation. pH = -log 10 [H +(aq)] WebNot necessarily the sophisticated mental gymnastics that we can do when it comes to understanding other people's intentions and motivations, but there is some evidence by primatologists and others, finding that there are some forms of empathy, including care, concern, in different types of animals such as in primates and even rats. designer infographics https://2brothers2chefs.com
