## How do you calculate pH solution?

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].

## Does NaOH have a high pH?

NaOH is a stronger base than NH3, so the NaOH solution would have the highest pH followed by the NH3 solution. Therefore, the ranking from highest to lowest pH for solutions with the same solute concentrations is: NaOH > NH3 > HC2H3O2 > HCl.

## How do you calculate the pH of HCl?

Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the chloride ion Cl–, would also have a concentration of 0.100 M.) The pH is thus –log(0.100) = 1.000.

## How do you calculate the pH of NaOH?

Calculating pH. To calculate pH, apply the formula pOH = -log[OH-]. Work out -log[0.1] = 1. Next, apply the formula pH + pOH = 14. To isolate the pH, work out 14 – 1 = 13. The pH of your NaOH solution is 13.

## What is the pH level of NaOH?

Using a pH indicator strip will tell you that NaOH (sodium hydroxide) is a strong alkaline. This means it has a pH toward the top end of the pH scale, which ranges from 0 to 14.

## What is the specific gravity of NaOH?

Specific Gravity: Sodium hypochlorite produced by a continuous process will have approximately 0.2% by weight excess sodium hydroxide, resulting in a specific gravity of 1.160 at 120 gpl

## What is the weight of NaOH?

Molar mass of NaOH is 39.99711 ± 0.00037 g/mol Compound name is sodium hydroxide Convert between NaOH weight and moles
