1. The relationship between pH and pKa is expressed by the formula: pH = pKa + log([A-]/[HA]).2. This equation indicates that a lower pKa value signifies a more acidic substance.3. Conversely, a higher pKa value indicates a weaker acidity in the substance.4. Consequently,...
pH = pKa°-logC酸 / C盐 (1) 这就是计算一元弱酸及弱酸盐组成的缓冲溶液pH值的通式。 2 由弱碱及弱碱盐组成的缓冲溶液 设弱碱的浓度为C碱(mol·L-1),弱碱盐的浓度为C碱(mol·L-1),在溶液中存在下列平衡: B + H2O BH+ + OH- [2] ( P140) 平衡时: C碱-x C盐+xx Kb°= x(C盐+x)/...
-log[H+] =-logKa°-logC酸 / C盐,所以 pH = pKa°-logC酸 / C盐 (1) 这就是计算一元弱酸及弱酸盐组成的缓冲溶液pH值的通式。 2 由弱碱及弱碱盐组成的缓冲溶液 设弱碱的浓度为C碱(mol·L-1),弱碱盐的浓度为C碱(mol·L-1),在溶液中存在下列平衡: B + H2O BH+ + OH- [2] ( P140) 平...
Calculate pH by using the pH to H⁺ formula: pH=−log(0.0001)=4pH=−log(0.0001)=4 Now, you can also easily determine pOH and a concentration of hydroxide ions using the formulas: pOH=14−4=10[OH−]=10−10=0.0000000001 pOH[OH−]=14−4=10=10−10=0.0000000001 Of cours...
\(pH = pKa + log_{10}\dfrac{[A^{-}]}{[HA]}\) This means that given an acid's pKa and the relative concentration of anion and "intact" acid, you can determine the pH. Ka values can be easily looked up online, and you can find the pKa using the same operation as for pH if...

pKa - The pKa value is the negative base -10 logarithm of the acid dissociation constant (Ka) of a solution. The quantitative behavior of acids and bases in solution can be understood only if their pKa values are known. To learn more about Calculation o
pKa and pH - The fundamental distinction between pKa and pH is that pKa denotes an acid's dissociation, whereas pH denotes a system's acidity or alkalinity.
