Four solutions of an acid dissolved in water are sketched below, as if under a microscope so powerful individual atoms could be seen. The same volume of solution is shown in each sketch. Rank the solutions by the strength of the dissolved acid. That is, select 1 under the solution of the strongest acid, 2 under the solution of the next strongest acid, and so on. = H₂O Note: Solution 1 (Choose one) Solution 3 (Choose one) ▼ Solution 2 (Choose one) Solution 4 (Choose one) X

plese don't handwritten solution..

QUES TION 4 The pH value is an expression of the molarity of H30 ions in solution. This concentration has strong impact on chemical reactions. The molarity is very small value, and therefore awkward to use. The pH scale simplifies this concentration making communication easier and faster. Demonstrate the relationship between pH and H30 molarity, using the formula, pH = -log(H30) where ) indicates concentration in molarity of a substance. What is the pH of a solution, having the H30* concentration of 0.00014 M?

Plz answer each part

can you help me on the second problem please

Each row of the table below describes an aqueous solution at about 25 °C. Complete the table. That is, fill in any missing entries in the second and third columns. Be sure each entry you write includes the correct number of significant digits. [1,0] H,O solution pH x10 A 1.2 X 10 mol/L mol/L 10.46 0.16 mol/L

A solution of sodium cyanide, NaCN, has a pH of 12.00. How many grams of NaCN are in 315 mL of a solution with the same pH?

For many weak acid or weak base calculations, you can use a simplifying assumption to avoid solving quadratic equations. x2 x- .2 [HА] — х [HA] Classify these situations by whether the assumption is valid or the quadratic formula is required. Assumption is valid Quadratic formula is required Answer Bank [HA] = 0.05 M Ka = 1 x 10-4 [HA] = 0.005 M Ka = 1 x 10-4 [НA] 3D 0.05 М Ka = 1 × 10-3 [HA] = = 0.005 M [HA] = 1 M Ką = 1 × 10-5 Ka = 1 × 10-3

Each row of the table below describes an aqueous solution at about 25 °C. Complete the table. That is, fill in any missing entries in the second and third columns. Round your entries for [H₂O*] to 2 significant digits, and your entries for pH to 2 decimal places. solution A B с [H₂O*] -6 6.5 × 10 mol/L mol/L 8 6.6 X 10 mol/L pH 0 9.24 0 x10 X Ś
