Investigating the solubility of Group II hydroxides Jiyeon Kim Aim: To investigate the solubility of Group II hydroxides (Mg(OH)2‚ Ca(OH)2‚ Sr(OH)2‚ Ba(OH)2) Research Question: What is the trend of solubility of Group II hydroxides going down the group as determined through measuring the volume of hydroxides needed to titrate with a known concentration of hydrochloric acid? Background Information: Solubility is when a solute forms a homogeneous solution by dissolving in solvent. The solubility of any

Each year‚ on average‚ there are 105 snowstorms. Salt is driven around in millions of trucks across the country to help deice the roads to make way for safe travels. In the United States‚ 20 billion pounds of salt are used every year to treat the icy roads after snowstorms. Common salt‚ the salt almost every American has on their dinner table‚ NaCl is most frequently used to deice roads across the country. Salt is very cost effective and efficient when used properly‚ however it is causing more harm

Salt Case Study Salt and Food We all need a little salt because it helps keep your body fluids at the right concentration. However‚ the majority of us eat more salt than we need. On average‚ people in the UK eat about 8.1g of salt a day. Even though it doesn’t sound like a lot‚ to reduce the risk of disease‚ adults should not be eating more than 6g of salt per day. A main source of salt is table salt. Your body only needs 1/4 teaspoon of salt every day. Salt is naturally found in foods but

This legendary American architect started a style of organic structures that remains a roadmap for the people of his genera today. His greatness not only remains by the buildings that he left behind‚ but through his school that he along with his wife started and his philosophy about designing. As a young child‚ Wright developed these characteristics

BACKGROUND: Esterification is a reaction that combines an alcohol with an organic acid‚ with a water molecule is being taken out‚ and an ester is formed. A concentrated acid catalyst speeds up the esterification. In this experiment set up‚ sulphamic acid was used‚ as it is a solid acid and be added dry‚ without any water‚ which is a reactant in this experiment equilibrium. Esterification is a slow and reversible reaction. The equation for the reaction between an acid RCOOH and an alcohol RẬᶦ

Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a

Salt and the effect it has on water. Do you like salt? Do you put it on your food to make it taste better? Salt doesn’t just make food taste better; it can change the freezing and boiling point of water. I bet you didn’t know that! There’s a reason for that‚ but I’ll explain that a little later. First‚ let’s find out if salt can actually change the freezing and boiling point of water. To do so‚ we need to do an experiment. Now‚ if you’re going to do an experiment‚ you’re going to need a hypothesis

Mahatma Gandhi proposed a non-violent march protesting the British Salt Tax‚ continuing Gandhi’s pleas for civil disobedience. The Salt Tax essentially made it illegal to sell or produce salt‚ allowing a complete British monopoly. Since salt is necessary in everyone’s daily diet‚ everyone in India was affected. The Salt Tax made it illegal for workers to freely collect their own salt from the coasts of India‚ making them buy salt they couldn’t really afford. Return to "India under British
