WebKOH is a strong base. Its conjugate acid, K+, has negligible acidity and will leave the pH at 7.00, a neutral solution. CH 3COOH is a weak acid, making its conjugate base, CH 3COO-a relatively strong base. It will produce a basic solution. a) KF b) KCN basic basic c) NaNO 3 d) RbI neutral neutral e) NH 4NO 3 f) Na 2CO 3 acidic basic WebThe balanced equation for the reaction in acidic solution is 14 H+ (aq) + 2 Mn2+ (aq) + 5 NaBiO3 (s) → 2 MnO4− (aq) + 5 Bi3+ (aq) + 5 Na+ (aq) + 7 H2O (l) There are 7 water molecules on the product side. Balance the following equation: K2CrO4+Na2SO3+HCl→KCl+Na2SO4+CrCl3+H2O

WebMay 4, 2016 · An end-chapter problem posed in an 11-grade texbook asks to analyse whether a water solution of CuSO4 will be acidic. The standard answer is yes, because " H X 2 S O X 4 is a strong acid, hence S O X 4 X 2 − is a weak base. As a weak base, it will not be too hot about grabbing H X + from the environment. On its part, C u X 2 + will strongly ... Web(c) chromium trichloride, CrCl3 (d) sodium hydrogen sulfate, NaHSO4. SOLUTION: (a) The ions are K+ and ClO4-, which come from a strong base (KOH) and a strong acid (HClO4). The salt solution will be neutral. (b) Na+ comes from the strong base NaOH while C6H5COO- is the anion of a weak organic acid. The salt solution will be basic. glypho-x supreme

WebIn more basic solutions where the hydronium ion concentration is less than $5.0×10^{-9}\;M$ (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are called acid-base indicators. Acid-base indicators are either weak organic acids or weak organic bases. WebSep 30, 2024 · The pH scale shows how acidic or basic a chemical is in aqueous solution (mixed with water). The scale funs from 0 (most acidic) to 14 (most alkaline or basic), where 7 is neutral pH. Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater than 7 up to 14 are bases.
