industrially is sodium thiosulfate. Sodium thiosulfate solution is sold in a range of concentrations. Dilute solutions of sodium thiosulfate can be used for cleaning contact lenses and used as a medicine for some cancer patients. Concentrated solutions are used to treat spillages of some chemicals. Sodium thiosulfate is safe to handle and store‚ but if it is mixed with an acid‚ a reaction happens. When dilute sodium thiosulfate is mixed with an acid‚ solid sulphur is made‚ which makes the solution appear

ACIDS‚ BASES AND SALTS 1. What are indicators? What are the different types of indicators? An indicator is a dye which changes colour when put into an acid or a base. The different kinds of indicators are- Natural indicators- Litmus is a natural indicator‚ litmus solution is a purple dye which is extracted from a plant called lichen. Litmus turns red in acidic solutions and blue in basic solutions. Other

the milk-dilute lemon juice solution relationship are complete opposites. The slop of the soda-antacid relationship is an upward increasing while the milk-dilute lemon juice relationship is a downward decreasing slope. 4. As more dilute lemon juice is added to the milk the milk becomes something called curled and the color dramatically changes. Also one of the things that changed was the pH‚ it went from 7.06 which is closer to neutral base and then decreased to 5.09 after 30mL of dilute lemon juice

moles of NaClO‚ and divide by volume of dilute bleach that was titrated in each trial to get M). 4. Calculate the molarity of the commercial bleach (not diluted) using your answer from step 3 and the M1V1 = M2V2 equation. (Use volume of concentrated bleach and total volume of dilute bleach) 5. Assume that the density of the commercial bleach is 1.08g/mL. Calculate the percent by mass of NaClO in the commercial bleach. (Start with molarity of concentrated NaClO found in part 4. Determine the molarity

------------ Zinc and hydrochloric acid In the lab‚ zinc granules react fairly slowly with dilute hydrochloric acid‚ but much faster if the acid is concentrated. The catalytic decomposition of hydrogen peroxide Solid manganese(IV) oxide is often used as a catalyst in this reaction. Oxygen is given off much faster if the hydrogen peroxide is concentrated than if it is dilute. The reaction between sodium thiosulphate solution and hydrochloric acid This is a

experiment‚ I expect to see different effects on potato samples depending on different water concentration: · After putting in dilute solution I expect their mass to increase‚ as effect of taking up water by osmosis - cell should become ‘turgid’. · Concentrated glucose solution - mass of potatoes samples should decrease ‚ due to water loss in plant cell after placing in concentrated water solution‚as the the number of water molecules diffusing out will be more than that entering. Cells become ’flaccid’
