If only 3.4 g of H2O is produced, what is the percent yield? Chemical compound. The conjugate base of a weak acid is a strong base. NH 4 Cl is slightly acidic. To tell if K2CO3 (Potassium carbonate) forms an acidic, basic (alkaline), or neutral solution we can use these three simple rules along with the neutralizati. Potassium Carbonate - Common Organic Chemistry The nitrogen in C 5 H 5 N would act as a proton acceptor and therefore can be considered a base, but because it does not contain an . SOLVED:Determine if each salt will form a solution that is acidic ... The nature of salt (acidic or basic) is . and CO3, isn't called carbonic acid, it is called carbonate.

K2503 is a stronger base than KHSO3 K2CO3 is a weaker base than KHCO3. Indicators are used to determine whether a solution is acidic or alkaline. So the answers must be: KCl = neutral (from HCl and KOH) NH4Br = acidic (from NH4 and HBr) K2CO3 = basic (from KOH and H2CO3) NaCN = basic (from NaOH and HCN) LiClO = basic (from LiOH and HClO) Tweet. and HCl is neutral salt. Show activity on this post. A weak acid and strong base produce a basic salt. Naming salts - Acids, alkalis and salts - AQA - BBC Monopotassium phosphate, with the chemical formula KH2PO4 or H2KO4P, is neither a base nor an acid but a salt.
