Which of the following has the highest concentration of sodium ion 0. 20 m NaCl 0. 13 m Na2SO4 0. 080 m Na3PO4?

A 0.20 M NaCl solution has [Na+] = 0.20 M; a 0.13 M Na2SO4 solution has [Na+] = 0.26 M; a 0.080 M Na3PO4 solution has [Na+] = 0.24 M. Therefore, the 0.13 M Na2SO4 solution has the highest sodium ion concentration.

What is the concentration of Na in NaCl?

Normal saline is 0.9\% saline. This means that there is 0.9 G of salt (NaCl) per 100 ml of solution, or 9 G per liter. This solution has 154 mEq of Na per liter.

Where is the highest concentration of potassium ions?

There is a higher concentration of potassium ions on the inside of the cell than on the outside. Each potassium ion (on either side of the membrane) is balanced by an anion, so the system as a whole is electrically neutral.

What is the concentration of sodium ions?

Therefore, the molar concentration of sodium ions is just 1 TIMES the molar concentration of sodium chloride. 1 times 0.110 equals 0.110. Therefore: [Na+] = 0.110. Na+ with square brackets around it is read as “molar concentration of Na+”.

How do you find the concentration of NaCl?

First, we must convert the mass of NaCl in grams into moles. We do this by dividing by the molecular weight of NaCl (58.4 g/mole). Then, we divide the number of moles by the total solution volume to get concentration. The NaCl solution is a 0.1 M solution.

What is the sodium ion concentration when 70.0 ml of 3.0 M na2co3 is added to 30.0 ml of 1.0 M nahco3 do this without a calculator group of answer choices?

Therefore, the total sodium ion concentration is 0.52 mol.

What is the concentration of potassium ions?

140 to 150 meq/liter
Potassium is the most abundant exchangeable cation in the body. It exists predominantly in the intracellular fluid at concentrations of 140 to 150 meq/liter and in the extracellular fluid at concentrations of 3.5 to 5 meq/liter.

How do you find the concentration of potassium ions?

Re: Finding the Concentration of a Specific Ion in Solutino Then, split each compound and calculate the total amount in moles of potassium ions, which is 0.0229 moles. Then find the concentration of the potassium ions by dividing the number of moles by the volume of water to get 0.0458mol/L.

What is the concentration M of sodium ions in 4.57 L of a 1.25 M Na 3p solution?

What is the concentration (M) of sodium ions in 4.57 L of a 1.25 M Na3P solution? Molarity/concentration is moles/ltr. so,1.25 M N a 3 P Na_3P Na3P means 1.25 moles of N a 3 P Na_3P Na3P in one litre of solution. 1.25 M Na3​P means 3 × 1.25 = 3.75 3 \times 1.25 =3.75 3×1.

What is the molar concentration of sodium ions in a .350 M na3po4 solution?

Thus, the molar concentration of Na+ is 1.05 M.

What is the maximum solubility of NaCl?

357 mg/ml
Solubility/Solution Stability: Maximum solubility of NaCl in water at 25°C is 357 mg/ml. NaCl is unusual in that its solubility does not increase appreciably with temperature, since at 100°C, the solubility is 384 mg/ml.
