2011年8月21日 · Anions of strong acids are such weak bases that they have no significant effect on the pH of a solution and are considered basic in water, why does KF have a pH greater …

2024年12月5日 · The pH of KF is larger than 7 because the typical acid for F- is HF which is a weak acid and its conjugate base is basic. Also, K is from group 1 which would typically be the …

2015年12月1日 · As we learned in titrations, strong acid and strong base together makes a neutral solution. For KF, it is KOH+HF produces KF. Like before KOH is a strong base. HF is a …

2017年7月30日 · "Determine whether an aqueous solution of each of the following salts has a pH equal to, greater than, or less than 7. If pH > 7 or pH < 7, write a chemical equation to justify …

2016年11月25日 · Homework 12.65 Postby Parsia Vazirnia 2L » Fri Nov 25, 2016 12:40 am Why is the answer to part D of 12.65 neutral and not basic with a ph>7?

2019年1月18日 · Ka is the ionisation constant, used when dealing with acids and excess protons in a solution. Kb is typically used with bases, and finding the pOH of a solution. Kc is just the …

2022年1月11日 · Kc is the equilibrium constant for any reaction, while Kw is specifically the equilibrium constant for water and its transformation into hydroxide and hydronium. Kw is …

2023年3月12日 · If we are shifting right, that means K > 1 and therefore Kf must be greater than Kr. That also helps explain why a temperature increase for an endo reaction causes the …

2019年12月4日 · The book mentions the formation constant Kf for finding equilibrium for coordination compounds. Do we need to know how to set this up the same way as the acids …
