worksheets include answers Dr Greenbowe has a Solutions of Acids Bases and Salts The pH of a solution expresses the concentration of hydrogen ions H + At a lower pH more hydrogen ions are in solution and therefore the solution is acidic Worksheet Have students use Answer The pH of water is generally neutral 7 and rainwater is slightly acidic 5-6 but acid rain is much more acid 2-6 and thus 17 When a metallic oxide is dissolved in water the solution formed has high concentration of ions 18 The salt of the sulphuric acid are called sulphates and those of the acid HNO₃ are called 19 is the process of decreasing the strength of an acid or base by hydrolysis 20 The pH range our body works is Answers 1 Question Two solution A and B were found to have pH value of 6 and 8 respectively The inference which can be drawn is that 1 the acid strength of the solution B is higher than that of A 2 A is an acid while B is a base 3 Both are acidic solutions 4 Both are basic solutions Ask if there were any

experiment we will use two different methods to prepare buffered solutions with the same assigned pH Buffer 1 will be prepared using acetic acid HC 2 H 3 O 2 and sodium acetate NaC 2 H 3 O 2Buffer 2 will be prepared using acetic acid HC 2 H 3 O 2 and sodium hydroxide NaOHBoth buffers will have a target pH of In the following circumference worksheets students are asked to find the area and circumference of the circles in inches It behaves as a very weak acid when comp The result is a perfectly balanced solution of salt and water with a ph of mixing a base with an acid results in a chemical reaction called neutralization Apply Once you know the concentration of a strong acid or a strong base you can estimate its pH Use pH = -log10H to calculate the pH of each of the strong acid

the K b will be very small However NH 4+ will lose an electron and act as an acid NH 4+ is the conjugate acid of NH 3 by the following reaction 784 N H 4 a q + + H 2 O l ⇌ N H 3 a q + H 3 O a q + This reaction produces a hydronium ion making the solution acidic lowering the pH below 7 An acid is a substance that forms a solution with a pH value of less than 7 whereas an alkaline substance has a PH level higher than 7 These are some of the things that we covered on substances Think you know your acids and The higher the pH value the more basic alkaline the solution The pH scale is based on a logarithmic scale powers of ten For example pH 7 is ten times more acidic than pH 8 pH 6 is 100 times 10 X 10 more acidic than pH 8 This means that even a small change in pH can significantly change the concentration of H+ ions in seawater First the sulfuric acid undergoes a reaction that reduces a portion of the H2SO4 to HSO − 4 and H3O + Second the HSO − 4 goes through its own reaction reducing a portion of it to SO2 − 4 the sulfate ion and additional H3O + The reason 05H3O + is not an accurate calculation for the concentration of the sulfate ion is the fact Answer aAcid any substance that in water solution tastes sour changes the colour of certain indicators eg reddens blue litmus paper reacts with some metals eg iron to liberate hydrogen reacts with bases to form salts and promotes certain chemical reactions acid catalysis b The main concept of importance is that those Your answers are 900 898 901 200 and 1300 final ph a 2 drops of 010m hcl are added 898 b 1 drop of 010m naoh is

of an acidic solution increases with dilution and the pH values of a basic solution decrease with dilution It is because by dilution the concentration of the H+ ions of acid reduces and concentration of the OH- ions of a base reduces Q10 Arrange these in increasing order of their pH values- NaOH blood lemon juice CBSE 2008 F For example a solution with a pH of 3 has a 1000 times greater
