Jose’s lab instructor gives him a solution of sodium phosphate that is buffered to a ph of 4. because of an error that he made while calibrating the ph meter, jose’s measurements of the ph of the sodium phosphate solution are 5.4, 5.4, and 5.4. what statement best describes his results

Needthe meter is the standard unit for: 1) height 2) length 3) weight 4) mass

Electrons are extremely important to what area of technology? a) anti-aging research b) household product development c) electronics d) drug discovery

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl +4h2o enter the elemental symbol. view available hint(s) is reduced
