simon43 Posted January 8, 2014 Share Posted January 8, 2014 My previous posts about magnets and British coins met with a great response! I've been able to find some small magnets and I have relieved several Brits of their life savings in small coinage Thanks to everyone who helped me to locate these items. My next quest is for books of Ph paper. These are typically used in school science experiments to gauge how acid or alkaline a liquid is. My initial point iof call was to a swimming pool supplier, but so far they all responded that they use more sophisticated means to measure the water Ph value, such as mixing tablets etc. Does anyone know where I can buy simply strip books of Ph paper? Thanks Simon Link to comment Share on other sites More sharing options...

harrry Posted January 8, 2014 Share Posted January 8, 2014 You may be able to get phenothylene and make your own ph strips. Similar in effect to litmus. http://en.wikipedia.org/wiki/Phenolphthalein Link to comment Share on other sites More sharing options...
Gregory Morozov Posted January 8, 2014 Share Posted January 8, 2014 There is a lot of educational difference between using phenolphtaleine (with which you cannot test acidity anyway, only alkalinity) and a proper pH test paper. Link to comment Share on other sites More sharing options...
harrry Posted January 8, 2014 Share Posted January 8, 2014 (edited) There is a lot of educational difference between using phenolphtaleine (with which you cannot test acidity anyway, only alkalinity) and a proper pH test paper. Well maybe he should use cabbage water. http://www.rsc.org/learn-chemistry/resource/res00000422/making-a-ph-indicator Although he can test acidity with it. It is colourless in the presence of an acid. http://encyclopedia.kids.net.au/page/ph/Phenolphthalein Edited January 8, 2014 by harrry Link to comment Share on other sites More sharing options...

harrry Posted January 8, 2014 Share Posted January 8, 2014 I know you are very qualified to teach science,,,I wish you were teaching in my nieces new school (why not move to Chiangrai they pay round 35000 and are advertising) but you may not have seen this which may help with lack of materials. http://www.scribd.com/doc/19241884/Science-Experiments Link to comment Share on other sites More sharing options...
