What are the four basic functions of a computer system? Your equation should show a proton transfer to form carbonic acid and a salt. Get access to this video and our entire Q&A library, What is Salt Hydrolysis? m = molality of the solute in mol solute/kg solvent. The equation for K3PO4 is:H3PO4 + KOH = K3PO4 + H2OIt is also useful to have memorized the common strong acids and bases to determine whether K3PO4 acts as an acid or base in water (or if it forms a neutral solution).Strong acids: HCl, H2SO4, HNO3, HBr, HI, HClO4Weak acids: HF, CH3COOH, H2CO3, H3PO4, HNO2, H2SO3Strong Bases: LiOH, NaOH, KOH, Ca(OH)2, Sr(OH)2, Ba(OH)2Weak Bases: NH3, NH4OHNote that we are talking about whether K3PO4 is an acid, base, or neutral when dissolved in water.- Salts of strong bases and strong acids: pH will remain neutral at 7.- Salts of weak bases and strong acids: pH less than 7 (acidic).- Salts from strong bases and weak acids: pH greater than 7 (alkaline).Based on these rules, the solution of K3PO4 dissolved in water is Basic.For polyprotic acids (e.g. This is the solution concentration in moles per liter. Explain how gene regulation makes cell specialization possible. i = van 't Hoff factor. Therefore 2.25 mol of {eq}\rm K^+{/eq} ions and 0.75 mol of {eq}\rm PO_4^{3-}{/eq} ions are formed.
