Sodium vs calcium acetate?
Why does sodium acetate have a pH of 8.9 and 0.2 M calcium acetate a pH of 7.6? Why such a large discrepancy?
Asked by Tod Budnik 6 months ago.
When a strong acid and a strong base are mixed together in equivalent amounts, you get water and a salt, and the resulting solution is neutral, pH 7.0. For example HCl + NaOH --> HOH + NaCl Because both the aid and base are strong (that is, completely ionized) they don't result in an excess of either protons our hydroxide ions. If you mix a strong base and a weak acid, you get a solution that is slightly basic, and if you mix a weak base and a strong acid yu get--guess what--a solution that is slightly acidic. Acetic acid is a weak acid and sodium hydroxide is a strong base, so the solution of the salt you get (sodium acetate) is basic. Here's why: the sodium ion is completely ionized, but since acetic acid is a weak acid, not all of the acetate ion exists as in its ionic form. Some reacts with the eater to form a bit of the un-ionized acetic acid and hydroxide ions, which make the solution basic: OAc- + HOH -----> HOAc + OH- (where OAc- is meant to inducate the acetate ion). Calcium hydroxide is a weak base, so you have a weak acid and a weak base (but not equally so) reacting to give you calcium acetate. To find which side of neutral this will fall, you need to know how weak the acid and base are relative to one another (the dissociation constants) and remember as well that calcium acetate is Ca(OAc)2 as calcium is a divalent ion (Ca++), that is you're getting two acetates for every calcium ion.

What you should do is start reading ingredient labels. This is very eye-openning. You will notice that many brands of dog foods are basically the same. Purina and Iams are very similar foods. If you want to pick the best food for your puppy, make sure the first ingredient is meat. Not meat meal, meat-by-product, bone meal, etc.(In fact, I like to choose a food that does not have meat meal anywhere in the ingredients!) Meat meals are just animal parts and you don't even know what animals. That's gross. You want to pick a meat that is named, like chicken, lamb, salmon, etc. Also, be aware that grains such as corn and rice are just fillers and offer no nutritional value. They should be farther down the ingredient list. I prefer to pick a food with no corn. Just read the labels. You'll be able to see how these foods compare. Don't pay attention to the marketing. Be aware that while some of the foods the others suggested are excellent quality, they have very high protein contents. Some are too high. If your dog is not extremely active, i.e. doing agility, herding, working on a farm. The dog does not need a food that high in protein. Some of those foods have protein levels around 50%. For the normal, everyday, pet dog, that's too much. You'll probably wanty to stick to something that is closer to 25-30% protein. Good luck. And also, these foods might cost a little extra, but you won't have to feed as much. You feed less because the ingredients contain more nutrients and less fillers. They will be better in the long run. Answered by Julietta Coale 6 months ago.

Chem Help please! Calculate the number of grams of solute in 225.8 mL of 0.219 M calcium acetate?
If anyone knows how to work it out, it would be help me practice. thank you so much!!!
Asked by Rosanna Yasurek 6 months ago.
calcium acetate is C₄H₆CaO₄ molar mass C₄H₆CaO₄ = 158.17 g/mol molarity (M) = (moles of solute / 1 liter of solution) 0.219 M calcium acetate solution means '0.219 moles C₄H₆CaO₄ per liter of solution' Using those facts and converting the mL to L, the number of grams solute is (0.219 moles C₄H₆CaO₄ / 225.8 mL) x (1000 mL / 1 L) x (158.17 g C₄H₆CaO₄ / 1 mole C₄H₆CaO₄) = 153 g C₄H₆CaO₄ ………………… to 3 significant figures ~~~~~~~ I used 3 sig figs in the final answer to match the given info of 0.219 moles, which has 3 sig figs. I was tempted to add one more digit, but that's against the sig fig rules. The actual calculated result was 153.406… I'll leave the decision about how many digits in the final answer up to you.

Asked by Vi Stempel 6 months ago.
Calcium acetate (molecular weight = 158.17 g/mol) c = n/v solving for n, therefore n = cv n = 0.207 mol/L x 0.1665 L n = 0.0345 mol of calcium acetate mol = mass/molar mass solving for mass, therefore mass = mol x molar mass mass = 0.0345 mol x 158.17 g/mol mass = 5.45 grams of calcium acetate Answered by Terrell Shorthair 6 months ago.

When 59.5 moles of calcium acetate are dissolved in enough water to make 131.9 milliliters of solution, what is the molarity of acetate ions? Answer in units of M
Asked by Theda Naugher 6 months ago.
The tricky bit here is the formula of calcium acetate. Since calcium is in group 2, each mole of calcium acetate will contain TWO moles of acetate ions. 59.5 moles of calcium acetate is an awful lot. (it turns out to be over 9 kilograms.) No way could you dissolve 9 kilos of calcium acetate in 131.9 ml There must be a facctor of 1000 somewhere that you've missed.

Find the molar mass of calcium acetate...158.165g. So start with 255g Calcium acetate x 1 mole Calcium Acetate/158.165 g Calcium Acetate x 6 mol Hydrogen/1 mole Calcium Acetate x 6.022e23 atoms/mole. So...(255 x 1 x 6 x 6.022e23)/(158.165 x 1 x 1) = 5.825e24 hydrogen atoms. Answered by Daria Spanswick 6 months ago.

Asked by Merna Yap 6 months ago.
Answer The expression for elevation of boiling point is Delta t = kb*m Kb is molal boiling point elevation constant, for water it is 0.512degc/m, m = molality of solute Delta t = 2.4 deg c (given), delta t = 0.512*m therefore, m=2.4/0.512 = 4.6875 moles / kg solvent Moleccular mass of calcium actate is 158.17 g /mol. Given soln therefore, contains 4.6875*158.17 gm / 1000 gms water = 741.42 gms calcium acetate / 1000 gm water 275 gm water would therefore , contain 741.42*275/1000= 203.9 gm calcium acetate Answered by Marybelle Arab 6 months ago.
