pH is defined as:
pH = -log[H+]
where '-log' is the negative of the mathematical function log base 10, 'log10' and [H+] is the concentration of hydrogen ions or hydronium (H3O+) in mol dm-3
If you can work out the concentration of H+ ions in aqueous solution, put it into the pH equation to work out pH.
It's useful to know that 'p' in physical chemistry generally means '-log', so pKa is equal to -logKa.

What percentage concentration is 60 grams per liter sulphuric acid?
The percentage concentration of a solution can be calculated by dividing the mass of the solute by the total mass of the solution and then multiplying by 100. In this case, if 60 grams of sulfuric acid are dissolved in 1 liter of solution, the concentration would be (60g/1000g) x 100 = 6%.
Using the Kw equation how is it possible to determine whether an aqueous solution is acidic basic or neutral?
By calculating the concentration of hydronium ions and hydroxide ions in the solution and comparing them to the equilibrium constant for water (Kw = 1.0 x 10^-14 at 25°C), you can determine the pH value of the solution. If [H3O+] > [OH-], the solution is acidic; if [OH-] > [H3O+], the solution is basic; and if [H3O+] = [OH-], the solution is neutral.
What (at standard pressure) is the temperature at which saturated solution of NH4Cl has a concentration of 60. g NH4Cl100. g H2O?
The solubility of NH4Cl at 20°C is approximately 74 g/100g water. Therefore, a saturated solution with a concentration of 60 g NH4Cl/100 g H2O would be below the solubility limit at that temperature.
What is the Viscosity of 60 sugar and 40 water solution?
The viscosity of a 60% sugar and 40% water solution will depend on factors such as temperature and sugar concentration. Generally, increasing the sugar content will increase the viscosity due to the additional dissolved solids in the solution. It is recommended to use viscosity measurements to determine the exact viscosity of a specific solution.
How many grams of crystals will b formed if a saturdayed potassium nitrate solution is cooled from 60 to 30?
The amount of crystals formed will depend on how much potassium nitrate was dissolved in the solution to begin with. As the solution cools from 60°C to 30°C, potassium nitrate will begin to crystallize out of the solution. The exact amount of crystals can be determined by calculating the solubility of potassium nitrate at 30°C and comparing it to the initial concentration in the solution.

What is the percent concentration by mass of a solution 4.2g of NaNO3 in 60 g water?
The total mass of the solution is 4.2g NaNO3 + 60g water = 64.2g. The percent concentration by mass of the NaNO3 in the solution is (4.2g / 64.2g) * 100% = 6.54%.
How many cc is 60 mg?
That depends on:The density of the substance (if it is pure); orThe concentration of the substance (if it is a solution)
What (at standard pressure) is the temperature at which saturated solution of NH4Cl has a concentration of 60. g NH4Cl100. g H2O?
The solubility of NH4Cl at 20°C is approximately 74 g/100g water. Therefore, a saturated solution with a concentration of 60 g NH4Cl/100 g H2O would be below the solubility limit at that temperature.
When 20 milliliters of 1 M HCL is diluted to a total volume of 60 milliliters the concentration of the resulting solution is?
The final concentration of the solution is 0.33 M. This is determined by using the formula for dilution: C1V1 = C2V2, where C1 is the initial concentration (1 M), V1 is the initial volume (20 mL), C2 is the final concentration, and V2 is the final volume (60 mL). Solving for C2 gives you 0.33 M.

What is the approximate pH of 60 grams per liter sulfuric acid?
The pH of a 60 grams per liter solution of sulfuric acid would be close to 0. This is because sulfuric acid is a strong acid that ionizes completely in solution, leading to a high concentration of hydrogen ions and a low pH.
How many mg of Magnesium will reqiured to prepare 60ml of 20 percent solution?
To calculate the mass of magnesium needed, use the formula: mass of solute = volume of solution (ml) x percentage concentration / 100. In this case, it would be 60 ml x 20% = 12 g or 12,000 mg of magnesium will be required to prepare 60 ml of a 20% solution.
Is it possible to mix a 10 percent acid solution and a 40 percent acid solution to obtain a 60 percent acid solution?
No. The reulting concentration (percent) must be between the two components. So, with the two acids you are mixing, you cannot get an acid that is less than 10% or more than 40%
What is the solution for 35 percent of 60?
35% of 60= 35% * 60= 0.35 * 60= 21
