What is the pH of the NaOH solution when 0.04 g of it is dissolved in water and made to 100 ml solution?

Calculate the pH of the following solutions. a. 0.37g fo Ca(OH)_(2) dissolved in water to give 500 ml solution b. 0.3 g of NaOH dissolved in water to give 200 ml solution c. 0.1825% HCl aqueous solution d. 1 ml of 13.6 M HCl is diluted with water to give 1 litre solution.

A 0.518 g sample of lime stone is dissolved in HCl and then the calcium is precipitated as CaC_2O_4 After filtering and washing the precipitate, it requires 40.0 mL of 0.250 N KMnO_4 solution acidified with H_2SO_4 to titrate it as, MnO_(4)^(-)+H^(+) +C_(2)O_(4)^(2-) rarr Mn^(2+)+CO_(2)+2H_(2)O The percentage of CaO in the sample is:

The ammonia evolved by the treatment of 0.30 g of an organic compound for the estimation of nitrogen was passed in 100 ml of 0.1 M sulphuric acid. The excess of acid required 20 mL of 0.5 M solution hydroxide solution for complete neutralization. The organic compound is

A quantity of 25.0 mL of solution containing both Fe^(2+) and Fe^(3+) ions is titrated with 25.0 mL of 0.0200 M KMnO_(4) (in dilute H_(2)SO_(4) ). As a result, all of the Fe^(2+) ions are oxidised to Fe^(3+) ions. Next 25 mL of the original solution is treated with Zn metal finally, the solution requires 40.0 mL of the same KMnO_(4) solution for oxidation to Fe^(3+) .
