Would you expect citric acid (formula weight = 192 g/mol) to have a melting temperature greater than that of lauric acid (formula weight = 200 g/mol)? Why or why not?
The chemical formula is the expression of the composition of the compound. We can express it in two ways, which are the structural or molecular formula and the empirical formula. For one, the empirical formula shows the elements present in the compound and the least possible subscript that maintains the ratio between the elements.
See Answer. Question: 7. Citric acid has the molecular formula HOC (CH.COOH),COOH and contains three carboxylic acid groups (-COOH). Calculate the molecular weight of citric acid. 8. Explain why three hydrogen atoms are acidic in citric acid. Show transcribed image text. Here’s the best way to solve it.
Assume the total mass of the compound is 100 grams to find the mass of each element in grams. Citric acid, the compound responsible for the sour taste of lemons, has the following elemental composition: C, 37.51 %; H, 4.20%; 0,58.29%. Part A Calculate the empirical formula of citric acid. Express your answer as a chemical formula.
Citric Acid: Citric acid is a weak organic acid in nature, and its chemical formula is {eq}\rm {C_6}{H_8}{O_7} {/eq}. It is mainly used as an acidifier, basically as a flavoring and a chelating agent. Citrate is a derivative, conjugate base, of citric acid. Answer and Explanation: 1
Aconitic acid is an organic compound with the formula C 6 H 6 O 6 and the IUPAC name propene-1,2,3-tricarboxylic acid. It contains a 3-carbon backbone with a double bond between two of the carbon ...
Underline answer. Citric acid, the compound responsible for the sour taste of lemons, has the following elemental composition: 37.51% carbon, 4.20% hydrogen, 58.29% oxygen. The molar mass of citric acid is 192.12 g/mol. Determine the molecular formula of citric acid. Underline answer. There are 2 steps to solve this one.
4: pH at first equivalence point = (Ka1 + Ka2) / 2 = (3.125+4.77) /2 = 3.947 (answer) pH at second equivalence point = (Ka2 + Ka3) / 2 = (4.77 + 6.40) /2 = 5.585 (answer) During the 3rd equivalence point all of the C6H8O7 is converted to salt C6H5O73- (aq). Since citric acid is a triprotic acid and both citric acid and NaOH have same ...
Your solution’s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on. Question: Citric acid monohydrate has the formula of C6H8O7•H2O. Therefore, it has 8 hydrogen atoms associated with the citric acid. Of these 8 hydrogen atoms, how many are acidic?
