This excel document includes an interactive neutralization reactions worksheet and the corresponding key. The students are asked to balance, identify the formula and phase of the salt formed, and name the acid, base, and salt in 18 neutralization reactions. As students input their data into the spreadsheet, they will receive immediate feedback as to if their answer is correct (they will gain a point) or incorrect (they will not receive a point). The sheet also automatically gives a percentage and letter grade for the worksheet as they progress through each reaction.
Content Covered on Worksheet:
The worksheet covers 36 common acids and bases taught in general chemistry. Many cations were chosen because of their application when teaching solubility rules (i.e. lead, silver, mercury).
The worksheet covers the following 18 common acids - HF, HCl, HBr, HI, H2S, HNO3, HNO2, HClO, HClO2, HClO3, HClO4, H2SO4, H2SO3, H3PO4, H3PO3, H2CO3, HC2H3O2, and HCN.
The worksheet covers the following 18 common bases - LiOH, NaOH, KOH, RbOH, CsOH, Be(OH)2, Mg(OH)2, Ca(OH)2, Sr(OH)2, Ba(OH)2, Al(OH)3, Hg2(OH)2, Hg(OH)2, Zn(OH)2, AgOH, Pb(OH)4, Pb(OH)2, and NH4OH.
The worksheet covers the following solubility rules -
(1) All Group 1A, NH4+, NO3-, C2H3O2-, ClO3-, and ClO4- ions are soluble.
(2) Br-, Cl-, and I- are soluble except with Ag+, Hg2+2, Hg+2, Pb+2, and Pb+4.
(3) SO4-2 ions are soluble except with Ba+2, Sr+2, Ca+2, Ag+, Hg2+2, Hg+2, Pb+2, and Pb+4.
(4) S-2 ions are insoluble except with Group 1A, NH4+, Ca+2, Sr+2, and Mg+2.
(5) Except rule #1, consider all remaining ions to be insoluble.
Suggested Grading (See PREVIEW for Reference):
As this is an interactive excel document, the worksheet is graded automatically as the students work through each reaction. It is based on the following grade scale...
100 - 93 (A), 92 - 85 (B), 84 - 75 (C), 74 - 70 (D), 69 - 0 (F)
I realize not all school systems use the same grade scale when assessing their students. Though you cannot change the grade scale within the document itself, you could advise students to use the percent/letter grade given as a guideline to how well they are progressing through the worksheet. I would then tell them how you do plan on grading the worksheet.
This worksheet really makes an excellent practice/review tool when teaching neutralization reactions. I would not recommend giving it for homework as it would be very difficult to assess whether a student actually completed their own excel document. However, you could get a mobile lab, go to a computer lab, upload it your website, etc where the students would have a chance to work through the worksheet either in your presence for a grade or at home for review.
To Save Paper:
The excel document is two pages in length. If you want students to print out their work, simply ask them to print two pages to a sheet where the first part of the worksheet will be on the left-hand side of the paper and the second part of the worksheet will be on the right-hand side of the paper.
STOP: Before you use this worksheet in your classroom, please copy the student version of the document to a new excel worksheet and save. If you don't, the students will also have access to the teacher key which is in the same excel document but on a different sheet.
*WARNING: This document does include a student copy and teacher key of the worksheet. However, both sheets are LOCKED and only certain cells are able to be typed in. I have done this because of the complexity of the formulas used in the sheet to get it to automatically grade items as they are being typed in. If you find any errors, please don't hesitate to message me. I will do whatever possible to help fix these errors before use in your classroom.
